     news.admin.net-abuse.misc charter
     news.admin.net-abuse.announce charter and guidelines

  1.1) What is news.admin.net-abuse.misc, and why was it created?
     news.admin.net-abuse.misc was created to replace
     alt.current-events.net-abuse and news.admin.policy. The former was
     one of the most widely read and respectable alt.* groups, while the
     latter had become largely a mess of messages cross-posted from
     a.c-e.n-a and news.admin.misc.
     news.admin.net-abuse.misc is, not surprisingly, for discussions of
     net-abuse (see "What is net-abuse", below): definitions,
     occurances, objections, complaints, battle plans, peace plans...
     Check out their charter in the appendix.
     NOTE: There is currently (July 1996) an RFD for splitting and
     reorganizing the news.admin.net-abuse.* groups. Watch news.groups
     for discussion or news.announce.newgroups for the Call For Vote.
  1.2) What is news.admin.net-abuse.announce, and why was it created?
     At the time of the newsgroup reorganization (early 1995),
     alt.current-events.net-abuse traffic amounted to dozens and dozens
     of messages every day. Many of these were pure speculation or
     kvetching, while many others were of the dreaded, hated, one-line
     "I saw this spam in rec.bedding.sheets, too!" breed. The messages
     of real importance to news admins, such as genuine spam
     announcements and spam-cancel announcements, were buried. Lots of
     people grumbled about this, and wanted a moderated group that was a
     digest of a.c-e.n-a.
     So in this writer's opinion, news.admin.net-abuse.announce's only
     purpose is to serve as that digest. During the voting, a couple of
     people were worried that the moderators of n.a.n-a.a would become
     some sort of legislative or judicial body. But they don't want to,
     and we don't want them to.
     Remember the Usenet way: "If they get carried away, we'll laugh at
     them and make fun of them and not let them play with our jacks."
     Check out their charter and guidelines in the appendix.
  1.3) What is net-abuse?
     Since the newsgroup's inception, many curious forms of Usenet
     behavior have been discussed on it. Of these, spam is the one most
     universally accepted as 'net-abuse', which is why it gets its own
     section below. Other Frequently Aired Complaints are discussed
     throughout the FAQ.
     However, as Neil Pawson says, "it's for abuse *of* the net, NOT
     abuse *on* the net." Just because somebody does something vile, we
     don't necessarily want to hear about it on n.a.n-a. To qualify as
     true panic-inspiring net-abuse, an act must interfere with the
     net-use of a large number of people. Examples of this: newsgroup
     flooding, widespread or organized forgery campaigns, widespread or
     organized account hackery, widespread or organized censorship
  1.4) What is the purpose of this FAQ?
     This FAQ is *not* intended as a comprehensive guide to netiquette.
     That is covered in RFC 1855. Many things that this FAQ appears to
     treat lightly are, in fact, extreme breaches of netiquette. The FAQ
     primarily attempts to answer: are these situations "net-abuse", in
     the sense that the whole world should hear about them?
  1.5) What questions does the FAQ leave unanswered?
     An infinite number, featuring:
     * What to do about e-mail spam (coming soon)
     * Who are the current net-abuse villains? or, Who is Jeff Slaton? or
       etc... (not really my bag--instead, see "Is there a blacklist of
       net-abusers?" below)
     I'd also love to have a section on network/address tracking and
     informational tools (telnet, traceroute, nslookup, etc.) a la "The
     Spam-tracker's Handbook". Whatever happened to that?
     Anyways, feel free to contribute whole new entries.
     Perhaps some of the other net-abuse-related FAQs can be wholly
     dumped into this one. -- J.D.
  1.6) Who's responsible for this FAQ?
     It's currently maintained by J.D. Falk (jdfalk@cybernothing.org),
     and was originally maintained by by Scott Southwick
     (scotty@bluemarble.net). The information has been gleaned from
     various Usenet sources --primarily posts to the net-abuse groups
     made by a wide variety of authors-- and so the maintainer must
     actively disclaim all responsibilty for the veracity, advisability
     and/or legality of anything contained in the FAQ. Thanks to the
     following people who have contributed to it, or at least discussed
     its contents in a non-threatening manner:

     Lamont Granquist, Victoria "Support Wench" Fike, Steve Patlan, Wilf

     others we have undoubtedly missed.
     Contributions are always warmly welcomed, as are suggestions,
     corrections and criticism. However, you know where to shove the
  1.7) Where can I get it?
     This FAQ will be posted thrice monthly (on the 1st, 11th, and 21st)
     to news.admin.net-abuse.*, news.admin.misc, news.groups.questions,
     and news.answers. It will also be available by anonymous ftp from
     rtfm.mit.edu and its mirror sites. The master hypertext version is
     available at:
  1.8) Is this the only Net Abuse FAQ?
     Unfortunately, the topic of Net Abuse is so vast and so
     controversial that it cannot be covered completely in one document.
     Of course, that didn't stop Daniel Barrett from trying, and doing a
     very good job. He wrote a book (published by O'Reilly Publishing)
     with the unfortunate but fitting title of Bandits on the
     Information Superhighway. More information is available at:
     Chris Lewis has written a draft FAQ titled Current Spam thresholds
     and guidelines, which describes exactly what the title says. It is
     posted weekly to news.admin.net-abuse.misc, but is not currently
     available on the web or via FTP.
     Gandalf (gandalf@digital.net) has written the alt.spam FAQ, or
     "Figuring out fake E-Mail & Posts," which focuses on how to track
     spam. It is available at:
     Another good document is Tim Skirvin's Cancel Messages FAQ, which
     is available in HTML at:
     or in ASCII at:
     To answer all those questions about Richard Depew and others
     cancelling misplaced binary postings, Shaun Davis-Gluyas has
     compiled the Bincancel FAQ, at:
     For an almost totally different viewpoint, see Dave Hayes's
     long-awaited document, "An Alternative Primer on Net Abuse, Free
     Speech, and Usenet," which at first denied the existence of this
     FAQ. You can find it and some related documents at:
     My answer to Dave's Alternative Primer is also worth reading:
     Then again, there's Ricardo H. Gonzalez's Introduction to
     news.admin.net-abuse.misc, which is unofficial in the sense that
     most of the people who really know what they're talking about when
     it comes to Net Abuse have pointed out glaring errors in that
     document, and he doesn't seem to care. For the most part, it is his
     own opinion (most FAQs try to be as factual as possible, or at
     least show a number of different opinions.) It also makes many
     references to a fictional "autocyberretromoderation bot," which
     will supposedly cancel any messages posted to
     news.admin.net-abuse.misc which do not fit some unknown secret
     criteria determined by some unknown secret cabal.
     The truth is, there is an ANTI-cancellation bot active on
     news.admin.net-abuse.misc -- any time a message in that newsgroup
     is cancelled, "Dave the Ressurector" will repost it, no matter who
     issued the cancel message. However, Mr. Gonzales does not believe
     this to be true, no matter how many times the evidence is
     If you wish to read his viewpoint, the document may still be at:
  1.9) I don't understand a single word of this.
     One of the best starting places for learning about Usenet is
     Indiana University's Usenet Resources page, at:
     [Scotty put that together at his old job, but doesn't maintain it
     any more.] It's got links to most Usenet primers, netiquette
     documents and news FAQs, Son-of-RFC-1036, some charters, newsreader
     man pages, etcetera.

  2.1) What is Spam?
     It's a luncheon meat, kinda pink, comes in a can, made by Hormel.
     Most Americans intuitively, viscerally associate "Spam" with "no
     nutritive or aesthetic value." The luncheon meat has its own
     newsgroup, alt.spam.
     The term "spam," as used on this newsgroup, means "the same article
     (or essentially the same article) posted an unacceptably high
     number of times to one or more newsgroups." CONTENT IS IRRELEVANT.
     'Spam' doesn't mean "ads." It doesn't mean "abuse." It doesn't mean
     "posts whose content I object to." Spam is a funky name for a
     phenomenon that can be measured pretty objectively: did that post
     appear X times? (See 3.1, "Yeah, but how many is X?')
     There have been "customized" spams--where each post made some
     effort to apply to each individual newsgroup, but the general
     thrust of each article was the same. A huge straw poll on
     news.admin.policy, news.admin.misc, and a.c-e.n-a (December 1994)
     showed that as many of 90% of the readers felt that cancellations
     for these posts were justified. So, simply put: if you plan to post
     the same or extremely similar messages to dozens of newsgroups, the
     posts are probably going to get cancelled.
     If you feel that a massive multi-post you are planning constitutes
     an exception, you are more than welcome to run the idea past the
     readers of news.admin.net-abuse.misc for feedback first.
  2.2) What is Excessive Multi-Posting (EMP)?
     Spam (and spam by any other name still stinks.)
     Some people feel that "spam" is an inappropriately misleading name
     for messages of this type. Others feel that "EMP" is misleading.
     Since spam is the most widely recognized term, that's what we use
     in this FAQ.
  2.3) What about cross-posting?
     Here's the difference between cross-posting and multi-posting:
     cross-posting is where you list all the groups on the Newsgroups:
     line of a single post. Multi-posting is where you have some idiotic
     program fire an individual copy of the post to each group. (If you
     do it manually, that's even more idiotic.) A cross-post only takes
     up the space of 1 post (one on every newsserver in the world), no
     matter how many groups; multi-posting takes up the space of dozens
     or hundreds of posts (on every newsserver in the world), which is
     why it infuriates so many people.
     So, cross-posting is better than multi-posting. It's still very
     often a bad idea, and if you get carried away it'll still get
     cancelled (see 3.2, "What is the Breidbart Index (BI)?")
     If you *must* cross-post, set the followups to a single appropriate
     group by adding a header line like:
     Followup-to: group.name.here
     This prevents the readers of all the groups from having to deal
     with the thread for weeks afterwards if the readers of only one or
     two of the groups take an interest in it.
     You can also add Followup-to: poster, which will (in most
     newsreaders) ask anybody who tries to follow up to e-mail you
  2.4) Where did the term 'Spam' come from?
     The prevailing theory is that it is from the song in Monty Python's
     famous spam-loving vikings sketch that goes, roughly, "Spam spam
     spam spam, spam spam spam spam, spam spam spam spam..." The vikings
     would sing this over and over, rising in volume until it was
     impossible for the other characters in the sketch to converse
     (which was, of course, a large part of the joke.)
     The term is rumored to have originated, as far as the Internet is
     concerned, from the MUD/MUSH community. Nathan J. Mehl, newsadmin
     for BBN Planet, tells the most reliable story known to date...
     Well, briefly summarized:
     My friend-who-shall-remain-nameless was, ah, a younger and callower
     man, circa 1985 or so, and happened onto one of the original Pern
     MUSHes during their most Sacred Event -- a hatching. After trying
     to converse sanely with two or three of the denizens, he came
     quickly to the conclusion that they area all of bunch of
     obsessive-compulsive nitwits with no life and less literary taste.
     (Probably true.)
     So, as the 'eggs' were 'hatching', he assigned a keyboard macro to
     echo the line:
     ...and proceeded to invoke it once every couple of seconds, until
     one of the wizards finally booted him off.
     ...which would have probably been that last that anyone ever heard
     or thought of it, except that it apparently ingrained itself into
     the memory of the PernMUSHers, and forever after there was the
     legend of 'that asshole who spammed us.'
     Every once in a while, this story makes it back to my friend, and
     he tries very hard to keep a straight face...
     Another theory is related to throwing a "brick" of the luncheon
     meat at a rotating metal fan. However, none of the long-time "spam
     watchers" have any idea where that theory was from before it showed
     up in a Time magazine article.
     The term wasn't first used to describe mass news posting, however.
     See the Hacker's Jargon File for previous uses of the word.
  2.5) Tell me about the Great Spammers.
     To paraphrase Yoda, spam does not make one great. However, a
     surprising number of people prefer infamy to obscurity, and would
     rather be hated than unknown. Some of those people take up spamming
     as a way to gain the notoriety that their warped psyches crave.
     So as not to duplicate effort, here's an excellent archive devoted
     to the various bug- and honey-bears of the Net:
     * The Kook of the Month site (particularly the Net.Legends FAQ)
     * The Net.Legends FAQ (html version)
     Not all of the kooks and legends discussed there are spammers, or
     even villains. Spam fans should pay particular attention to the
     entries on Serdar Argic, the spiritual ancestor of today's
  2.6) Who were Canter and Siegel?
     Unfortunately, it's "Who *are* Canter and Siegel?" They're lawyers,
     authors, and Usenet newbies _par excellence_. Super-newbies.
     Honorary Permanent Newbies. When they sit around the net, they sit
     *around the net*...
     C+S weren't the first spammers, but they were so gothically clumsy
     about it, and so intent on making a buck, that people were
     terrified and infuriated into starting alt.current-events.net-abuse
     (which has since been replaced by the news.admin.net-abuse.*
  2.7) Where can I get more information about them?
     The best archive of Canter and Siegel-related postings is
     maintained by C&S themselves; last time somebody checked with "ls
     -r", the fun-loving net.lawyers seemed to be storing every post
     that mentioned them (can you say "grepping for libel cases"?) It's
     worth noting that to date nobody has been sued by them for anything
     net-related, and probably not for anything else either.
     If you're not C or S yourself, though, the next best info source is
     Thomas Leavitt's "The Canter & Siegel Report," available via
     anonymous ftp from:
     Those files are zipped. Users with access to 1990s technology
     should check out the WWW versions at:
     There's also a wonderful article on the pair available at:
     http://www.eye.net/Howling/Kooks/Kreeps/CS2.htm (new URL 8/20/96)
     Many, many more docs are available, but I'll stop there, because
     there's really no reason to dwell on the past. In fact, Canter &
     Siegel have both posted to news.admin.net-abuse.misc and other
     groups from time to time (always multiposted -- they seem
     genetically unable to crosspost), and it has always been quite
     obvious that all they wanted was to generate more publicity for
  2.8) What should we do about the book?
     What book?
  2.9) Who is Cancelmoose[tm]?
     Cancelmoose[tm] is, to misquote some wise poster, "the greatest
     public servant the net has seen in quite some time." Once upon a
     time, the moose would send out spam-cancels and then post notice
     anonymously to news.admin.policy, news.admin.misc, and a.c-e.n-a.
     The Moose stepped to the fore on its own initiative, at a time (mid
     1994) when spam-cancels were irregular and disorganized, and
     behaved altogether admirably-- fair, even-handed, and quick to
     respond to comments and criticism, all without self-aggrandizement
     or martyrdom. Cancelmoose[tm] quickly gained near-unanimous support
     from the readership of all three above-mentioned groups.
     Nobody knows who Cancelmoose[tm] really is, and there aren't even
     any good rumors. However, the moose now has an e-mail address
     (moose@cm.org) and a web site (http://www.cm.org.)
     By early 1995, several others had stepped into the spam-cancel
     business, and appeared to be comporting themselves well, after the
     Moose's manner. The moose has now gotten out of the business, and
     is more interested in ending spam (and cancels) entirely (see "What
     is NoCeM?")
  2.10) Who are the current spam cancellers?"
     Chris Lewis and Robert Braver take care of most of the spam (John
     Milburn has retired from the spam-cancelling biz), while Richard
     Depew cleans up spews from horribly misconfigured news servers,
     large misplaced binaries, and the like. Benjamin "Snowhare" Franz
     sometimes takes care of MAKE.MONEY.FAST postings. Michael Scheidell
     and others deal with problems (usually out-of-area postings) in
     various local hierarchies.
     Overall, Chris Lewis is considered to be the expert on spam
     cancelling, and one of the experts on Usenet in general.
     For a good overview of who's doing what right now, hop over to
     news.admin.net-abuse.announce and check headers.

  3.1) Yeah, but how many times is 'X'?
     How many posts does it take to push the spam envelope? To use up
     all your spam charity points? For a bare-bones spam? To trigger the
     Among those who agree that spam should be defined solely by
                           -----------------> 20
          appears to be the magic number, or at least a number so
   middle-of-the-road that it provokes very little passionate dissent in
      either direction. Notably, Cancelmoose[tm] refuses to set a firm
    number, in the belief that people would simply post [X-1] messages.
   It's safe to say that a couple incidents of 19-post spams would cause
     the magic number to plummet. Thus, 20 should be considered a vague
                            approximation only.
    Passionately dissenting note: Rahul Dhesi [dhesi@rahul.net], one of
      the fathers of the cancel-bot movement, sticks by the following
     More than five physically distinct postings with substantially
     identical content posted within a period of ten days.
     The most reliable document describing current spam thresholds and
    guidelines is a draft FAQ posted weekly to news.admin.net-abuse.misc
    by Chris Lewis. It also describes the Breidbart Index (see below) in
   greater detail. That FAQ is not currently available on the web or via
  3.2) What is the Breidbart Index (BI)?
         The Breidbart Index (BI) is a measure of the breadth of any
       multi-posting, cross-posting, or combination of the two. BI is
     defined as the sum of the square roots of how many newsgroups each
     article was posted to. If that number approaches 20, then the posts
                   will probably be cancelled by somebody.
     For instance, four identical posts to nine newsgroups each (4 times
     3) has a BI of 12. However, nine identical posts to four newsgroups
     each (9 times 2) has a BI of 18.
  3.3) What is NoCeM?
     NoCeM is an end to all this spam, and an end to all this
     cancelling. With NoCeM (pronounced "No See 'Em"), your newsreader
     goes out and gets certain posts (from trusted parties) that contain
     lists of junk articles (ECP, spam, etc.) Your newsreader then hides
     those articles from you.
     Note that right now there's only a NoCeM newsreader for Unix.
     The move to NoCeM is headed by the Cancelmoose[tm] (moose@cm.org),
     and the moose's web site has all the info you might want about
     Also check out the newsgroup alt.nocem.misc, which will degenerate
     into a Big 7 newsgroup (news.lists.nocem?) one of these days.
  3.4) Is there a blacklist of net-abusers?
     Yes, Axel Boldt maintains the world-renowned "Blacklist of Internet
     Advertisers" at:
     Now, before you get really worried about McCarthyism and such, go
     and look at Axel's self-imposed rules for maintaining the
     blacklist. He's much fairer than most of those people deserve.
  3.5) How can I tell if a post is forged?
     Gandalf (gandalf@digital.net) has written the alt.spam FAQ, or
     "Figuring out fake E-Mail & Posts," which focuses on how to track
     spam. It is available at:
     For a rough article on forgery, originally constructed for this FAQ
     out of information contributed by Robert Bonomi, Arthur Byrne, Emma
     Pease, and Alan Bostick, see:
     For more information on headers, see RFC-1036, "Standard for
     Interchange of Usenet Messages," at:
  3.6) How can I tell how many newsgroups an article was posted to?
     For people who can't use the classic "grepping the newsspool"
     method, nn or nngrab may be able to help. (The following is adapted
     from a posting by Lee Rudolph--thanks.)
     You can force the Unix newsreader nn to ignore your .newsrc and
     create a "merged newsgroup" consisting only of articles containing
     a certain word in their subject line. For instance, to gather all
     articles at your site containing the word "spam" in their subject
     line, use this command:
     % nngrab spam
     That's basically a faster version of
     % nn -i -s"spam" -mXx
     Caution: this latter method can be a long, tedious process. See the
     nn man page for more details.
  3.7) My group is full of crap. Why isn't it being cancelled?
     Lots of groups are full of inappropriate posts, widely crossposted
     advertising, and so forth -- just pop into misc.misc or alt.sex for
     as many examples as you can possibly handle.
     As annoying as it may be, these posts may not be cancellable spam.
     Keep in mind that the cancel thresholds err in the favor of the
     excessive poster, and still leave *lots* of room to post in a
     manner that most people find inappropriate.
     A single, excessively crossposted post can not be cancellable in
     and of itself. In order for a single post to be cancelled, it would
     have to be posted to 400 groups (sqrt(400) = 20). This is not
     possible due to limits of news software.
     Robert Braver reports "When checking for spam, I often must pass
     over groups of messages that are likely considered off-topic
     intrusions in each of the newsgroups it is posted to, but it
     doesn't hit the cancel threshold."
     One good solution here would be for the newsadmins of a particular
     locality to come to a consensus for more stringent thresholds for
     their respective local hierarchies, as has been done in the atl.*
     and fl.* hierarchies.
     Of course, the messages may actually be cancellable spam,
     especially when you consider the current 45-day window. But, this
     type can be harder for the automatic spam detectors to find.
     Once a slow spam is detected and posted to
     news.admin.net-abuse.announce, it makes it easier to keep tabs on a
     particular poster or series of messages in the future. This kind of
     spam is probably where "field reports" to news.admin.net-abuse.misc
     are the most useful.
  3.8) OK, I'm certain it's spam. Who should I mail-bomb?
     Don't mail-bomb anybody. Harrassment is illegal everywhere. If
     somebody's done something truly evil, they'll get enough single
     responses from individuals to achieve the same effect.
  3.9) OK, I'm certain it's spam. What should I do?
       Check n.a.n-a.announce. If somebody's already made a definitive
     spotting, there's no sense in an "I've seen it, too" post.
       Include a *complete* header from one copy of the spam in your
     post to n.a.n-a.announce. Set followups to n.a.n-a.misc.
       Say how many newsgroups at your site it was posted to; list 20 or
     more of them. (See "How do I know how many newsgroups an article
     was posted to?")
       Complain politely to the spammer and the Usenet administrator at
     the spammer's site (whose address should be "usenet@site.name" or
     "news@site.name"; if that fails, try "abuse" or "postmaster".)
     Request that the Usenet administrator post a response to
     n.a.n-a.announce, detailing what actions have been taken. Again,
     remember to be polite -- it is rare that the administrators are in
     any way responsible for the message.
  3.10) What about e-mail spam?
     You can always complain about unsolicited e-mail to both the bozo
     that sent it to you and the bozo's postmaster. To write to a
     postmaster, just substitute the perp's username in their address
     (e.g., bozo@otherwise.lovely.com) with "postmaster" (i.e.,
     postmaster@otherwise.lovely.com.) Please be brief and polite with
     the postmasters, include a copy of the e-mail you received, and
     leave the subject-line intact (in case the postmaster wants to set
     up an auto-responder.)
     Be sure to include all the headers (not just From, To, Date, and
     Subject, which is the default in most mail programs) in your reply,
     just in case the e-mail was cleverly forged. That way, the
     postmaster can trace it back to its source if necessary.
  3.11) I e-mailed a complaint to so-and-so about their {post, mail}, and now
  they're threatening to complain to my system administrator. What should I do?
     Let your sys-admin know right away what's happening. Tell them the
     story, briefly. Offer to supply the post(s) in question, so that
     your admin doesn't have to go searching. Then keep them updated on
     any further threats.
     If you're brief, polite, and on the right side, you can usually
     find an ally in your sys-admin.
  3.12) List of Basic Administrative Addresses
     The search for the best person to complain to at any site has led
     to much speculation and arguments, even among admins at the same
     site. However, if a message to the original poster doesn't get you
     anywhere, somebody at one of the following addresses might be able
     to help.
          A lot of ISP's and network backbones have created 'abuse'
          addresses for complaints about net-abuse. That's usually the
          best place to start.
   usenet or news
          For Usenet abuse, you can usually reach a news administrator
          through one or both of these addresses. A notable exception is
          Compuserve, which utilizes the address
          RFC 822, the document which set most of the current standards
          for Internet e-mail back in 1982, makes it mandatory for all
          sites which pass e-mail to have a postmaster address so that
          problems can be reported. The purpose of postmaster has
          expanded at many sites to include net-abuse, both e-mail and
   Administrative or Technical Contacts
          If you have access to the whois command, you can type (for
          example) 'whois example.com' to find out who the administrative
          and technical contacts are for a domain. This will list their
          e-mail address, and often their phone and FAX numbers (but
          remember, be polite, because the contacts aren't usually
          responsible for their users' misbehavior, and harassment is
          illegal everywhere.)
   Upstream Providers
          If none of the above get you anywhere, you can try going to a
          site's upstream providers. For news, check the Path: header of
          the original message. To the right, you'll see the originating
          site. Each site between you and them is separated by an
          exclamation point, as in the partial example below:
          As you can see, the message originated at the machine
          foobar.mydomain.com. The next news hop is
          dummy-host.example.com, so you'd complain to news@example.com
          if the admins at mydomain.com were uncooperative.
          For e-mail, determining who's upstream can often be confusing
          -- many people get it wrong. Unless you're familiar with the
          whois and traceroute tools, I'd suggest not even bothering.
  3.13) What is a cancel-bot?
     First off, "cancel-bot" is an unfortunate misnomer, and one that
     the conventional media have understandably misunderstood. "Bot"
     implies that something is out there, running unattended, cancelling
     whatever meets its nefarious qualifications...but that is quite
     rare, and is only done when both the user and their administrators
     are completely unwilling to stop spamming. For the most part, all
     spam-cancels are sent out manually and deliberately by actual human
     beings. (They happen to use a program that is commonly referred to
     as a "cancel-bot".)
     A cancel-bot, misnomer aside, is a program that sends out cancel
     messages; you feed it the message-IDs of posts, and it sends out a
     cancel message for each one (see RFC 1036.) Cancel messages are
     normally sent out by a newsreader in response to a user's request
     to cancel a message, using a newsreader command, *if* the user was
     also the original poster of the message. Sites will ignore cancel
     messages that don't appear to come from the original poster.
     Cancel-bots work around this restriction by using header lines that
     make it look like the original poster sent out the cancel; they'll
     usually add something like a "Cancelled-By" header line as well, to
     keep things nominally above-board.
     Use of a cancel-bot against anything besides 'consensus spam'
     outrages people, as it should. See alt.religion.scientology for
     sample discussions.
     For more information on cancels (especially in regards to net
     abuse), Tim Skirvin has written a very good FAQ, available at:
  3.14) Where can I get me a cancel-bot?
     If you have to ask, you should probably wait a while. ;}
  3.15) How do the spam-cancellers cancel spam?
     * They make bloody sure they know how to use their cancel-bot;
     * They confirm the spam themselves;
     * They announce their action to n.a.n-a.announce. This prevents
       everyone from waiting around and wondering whether anyone's done
     Here's a standard section from a cancel-notification post by the
     beloved Cancelmoose(TM):
     The $alz cancel. and Path: cyberspam conventions were followed.
     [The $alz convention is to create your cancel message-ID by
     prepending 'cancel.' to the original one. The cyberspam convention
     is to use- 'Path: cyberspam!usenet' so that sites that do not want
     your cancels can easily opt out. Please use these when cancelling
  3.16) Can I sic The Man on these MAKE.MONEY.FAST losers (or other types of
  net abusers)?
     You can complain about e-mail or Usenet pyramid schemes (at least
     those involving Americans somehow) to the FTC:
  STAFF CONTACT:      Bureau of Consumer Protection
                      David Medine, 202-326-3224

     Before doing so, consider seriously whether you actually want to
     encourage government intervention. The number of 'net cases the FTC
     has been involved in is very low at this point; in an ideal world,
     it would probably remain that way.
     A non-governmental organization which deals in such things (and
     more) is the National Fraud Information Center, which is funded by
     grants from major corporations and works in cooperation with
     federal, state, local and international law enforcement agencies.
     Their purpose is organize, classify, and forward "stuff" to the
     appropriate body: state's a.g, FTC, FBI, Secret Service, wherever.
     Thus they are not "law enforcement" and the problems of inaction by
     local district attorneys, etc. persist (d.a's have "too much work
     to do" to go after an individual posting a chain letter). You can
     e-mail them at <nfic@internetmci.com>, or get information from
     their web page, which is at:
     For stock fraud and the like, some people have been complaining to
     the Securities and Exchange Commission at the address
     <enforcement@sec.gov>. I'm not sure if there've been any results
     from that corner, however.
  3.17) What is a killfile, and how do I use one?
     A killfile enables you to permanently avoid reading posts by
     certain people, or from a certain site, or whose Subject: lines
     contain particular words... Check out the RN killfile FAQ at:
     If your newsreader doesn't allow killfiling, write the author of
     the newsreading software and ask them to add support for killfiles.
     Although it doesn't discuss killfiling, see 'The "Good Net-Keeping
     Seal of Approval" for Usenet Software' at:
     for more information on what makes a good newsreader.
     And, for good advice on who to ignore, see the Global Killfile:
  3.18) How do I killfile all crossposted messages?
     It's becoming quite common for people to killfile all messages
     crossposted to more than X newsgroups, because this cuts down on
     the amount of blatantly off-topic crap they have to read.
     This is simplest to do in the rn family (rn, trn, strn, etcetera)
     using a killfile entry like the following:
     /^Newsgroups: .*,.*,.*,.*,.*,./h:, That one kills anything posted
     to more than six groups, plus all of the followups in that thread
     (that's what the comma at the end means.) For less groups, use less
     .* entries -- for more groups, use more.
     Peter Kappesser suggests a somewhat more efficient form for servers
     which support the Xref extension to the News Overview database file
     (if you aren't sure if your server supports it, just check and see
     if there's an Xref: header in the messages you see. If there is, it
     /:.*:.*:.*:.*:.*:/HXref:, In this, the number of colons equals the
     threshold number of groups. This is more efficient because the Xref
     header line is transferred with the NOV file when you enter the
     group, so trn can process it quickly. If you kill on the Newsgroups
     line, trn has to fetch from the server at least the header for
     every article in the group in order to examine it for the kill.
     One slight difference is that Xref contains only those groups
     carried by the server, which may not necessarily be all those
     listed in Newsgroups. However, this isn't often a problem -- most
     ECP's are to a dozen or more groups, so it doesn't matter that
     Newsgroups lists 27 groups while Xrefs only has 18, it's still
     greater than 6!
  3.19) What is the Usenet Death Penalty (UDP)
     There are two different things commonly referred to as "UDP."
     The one least argued about could be called "shunning" or
     "aliasing," in which a newsadmin (running INN unoff3 or above, or
     using the 'shun' patch to earlier versions of INN) can add a site's
     pathhost to their ME line. They simply won't get any messages from
     that site. Some may consider this censorship, but it fits quite
     well with the simple but often forgotten concept that a newsadmin
     can do whatever they want on their own machine so long as it
     doesn't cause any problems for other newsadmins.
     The other Usenet Death Penalty is automatic cancellation of all
     messages from a site, or from a person, or based on a regular
     expression. This is sometimes done when a spam (or spew) continues
     unabated even after the spam cancellers and other net-abuse
     activists have attempted to contact somebody and ask them to stop.
     As you can guess, there are arguments about this which have
     literally been going on for years.
     Currently, the general consensus among news.admin.net-abuse.misc
     participants is that UDP of either type should only be employed
     after every other method has been tried and failed.
     In the useless trivia column, the term "Usenet Death Penalty" was
     first coined by Eliot Lear. The first software to perform it was
     written three years earlier by Karl Kleinpaste in 1990, and was 28
     lines long. Karl is also known as being the author of the anonymous
     server software.
     The second (previous versions of the FAQ referred to it as the
     first) was written by Rich $alz (the inventor of INN) in Perl in
     April, 1993. It was 76 lines long, including instructions for use.
  3.20) Do all hierarchies have the same rules?
     Nope. This FAQ mainly deals with what's considered net abuse in the
     "Big 8" (comp.*, humanities.*, misc.*, news.*, rec.*, sci.*, soc.*,
     and talk.*) and alt.* (we also touch on biz.* a little bit.) But
     there are many hierarchies -- especially regional and local --
     which have begun to adopt much stricter policies on net abuse.
     The main reason behind this is that the local hierarchies usually
     have a smaller target audience. For example, dc.* exists for the
     Washington, D.C. metropolitian area, fl.* for the state of Florida,
     and so forth. Long ago in the history of Usenet (okay, it was only
     two or three years ago) all the news hosts in Florida traded fl.*
     with each other, and it didn't leak too far out-of-state -- but
     now, with so many national news providers, you can read fl.* pretty
     much anywhere in the world.
     The point, however, is that just because you have /access/ to a
     heirarchy doesn't mean your message is appropriate for it. Many
     locally oriented groups, especially *.forsale and *.jobs groups,
     are deluged with non-local messages, which are often crossposted to
     a large number of different, incongruent local heirarchies. While
     these don't individually set off alarms on the world's
     spam-watching software, they can make a group become useless for
     local postings because it's so hard to wade through all the
     misplaced stuff.
     So, most local hierarchies now have people (or, more often, groups
     of people) watching over them, sending copies of the FAQ or Charter
     to people who post inappropriately, and -- in extreme situations --
     cancelling the misplaced messages. Cancellation after the fact is
     commonly referred to as "retromoderation," and is still a topic of
     hot debate.
     For more specific information, the Regional Guidelines and Periodic
     Postings Database can be viewed at:
     Or, watch the group itself for a while to see if there're rules of
     any type. Remember that in this case, "a while" means at least two
     weeks, since FAQs don't get posted every day, and "but I saw other
     people advertising their thigh cream here!" is a really lame
     There is also a mailing list dedicated to discussing the mechanics
     and policies that regional FAQ maintainers and retromoderators
     follow. For more information, contact

  4.1) I hate net-cops like you people.
     Who will watch the watchmen? net-cop.cops like this, apparently. ;}
     Anyways, anyone who wanted to police the net would be a pig-headed,
     unrealistic fool. Thankfully, we (the regular participants in
     news.admin.net-abuse.misc) just want to shoot spam out of the sky,
     * We hate it,
     * It feels good, and
     * We can.
     Anyways, if you don't like spam being cancelled at your site, you
     can have your upstream feeds alias your site to "cyberspam".
     (Actually, you can only do that if you're the newsadmin -- but
     users are subject to the whim of their newsadmin anyway, so if you
     don't like your newsadmin's policies, you can always just build
     your own server and get a feed from someplace else.)
  4.2) Isn't cyberporn a bigger problem than spamming?
     No matter what the more sensationalistic media outlets may try to
     tell you, "cyberporn" is not a real problem. For more information,
     see cyberNOTHING's Cyberporn Report, at:
     As for illegal stuff, like child pornography -- there are existing
     laws against that in most countries, so those people will go to
     jail, and good riddance. But they are ruining Usenet in the
     Net abuse, as described in this document, is a big problem, and
     will continue to be a problem unless Something Is Done.
     Nevertheless, a case could be made that other issues
     (Government-imposed censorship, etcetera) are more or equally
     important. But that's not what this FAQ, or the net-abuse
     newsgroups, cover.
  4.3) Hey, I think my group's being invaded by alt.syntax.tactical!
     I'm sorry to hear that. Please don't bring that subject up again
     here. Good luck... Keith "Justified and Ancient" Cochran, who has
     been wrongfully accused of a.s.t involvement himself, adds: "I
     would suggest the first thing you do is take a chill pill." (Note
     that there is no second thing to do. However, you may want to pass
     the time reading the alt.bigfoot FAQ:
     --particularly the part about cats.)
     See also 3.15, "What is a killfile, and how do I use one?"
  4.4) Hey, I think my group's being invaded by the "Usenet Freedom Council!"
     The abusive "Usenet Freedom Council" seems to be made up of a
     number of accounts all owned & operated by Dr. John Grubor, a.k.a.
     Manus, a.k.a. DrG, a.k.a DrGodFuck, ad nausea infinitum. It used to
     include former Kook of the Month Steve Boursy, former Kook of the
     Month Bob Allisat, and former Kook of the Month Nominee Vladimir
     Fomin (who also no longer has access to the 'net under that false
     Now that news.admin.* people have pretty much unanimously killfiled
     him, he's started going to other newsgroups and attempting to get
     outraged responses from people by posting what can only be
     described as patent bullshit.
     The best thing to do is ignore him. This, of course, made easier
     with a good killfile (see 3.15, "What is a killfile, and how do I
     use one?") The REAL "Usenet Freedom Council" was dreamt up by Dave
     Hayes. The best way to understand it is to view his "Freedom
     Knights" home page, at: http://www.jetcafe.org/~dave/usenet/
     Afterwards, I'd suggest reading "Dave Hayes / Freedom Knights: An
     Alternative View," which some feel is a little more realistic (and
     there are even those who say it's being too nice.)
  4.5) Hey, somebody posted an ad in {newsgroup}!
     All right, all right: first, check to see if the post was obviously
     forged (see 3.5, "How can I tell if a post is forged?")
     Then check to see if it's spam (see 2.1, "What is Spam?" and 3.6,
     "How do I know when I've got spam on my hands?") It's probably not.
     We only want to hear about it if it's spam.
     If the ad is off-topic, and you really can't let it go, check out
     the advice in 4.6, "Hey, so-and-so's not being nice in
  4.6) Hey, so-and-so's not being nice in {newsgroup}!
     Happens all the time. We don't want to hear about it. However, here
     are some things you can do (written by Keith "Justified and
     Ancient" Cochran):
     "The first thing to do is take it up with user@some.site. If you
     can't achieve a mutual understanding, then you _MIGHT_ (note, not
     WILL, _MIGHT_) want to mail postmaster@some.site with your
     complaint. If you are going to write to postmaster@some.site, be
     sure to include the full, unedited post you have a problem with, a
     short but descriptive summary of why you have a problem with it,
     and a short, but descriptive explanation of what you would like to
     have happen. "Note that this does not apply to MAKE.MONEY.FAST. If
     you see a copy of M.M.F, just e-mail postmaster@some.site,
     including the article ID, and the first paragraph of the post."
     Of course, the descriptive explanation of what you would like to
     have happen must also be realistic. Since most ISP's have a policy
     regarding commercial posts, it's common to ask the postmaster to
     reiterate or reinforce whatever policy they may have on hand,
     rather than asking right away for the user to be nuked. It's not
     nice to tell system administrators what to do -- especially if you
     don't know the entire situation yourself.
     See also 3.15, "What is a killfile, and how do I use one?"
  4.7) Hey, the "Good Times" virus--
     ...is a total, 100%, long-proven hoax. For the complete story, see:
  4.8) Hey, there's this (AT&T, Jerry Garcia, whatever) banner message in the
  newsgroup descriptions!
     We know, we know... It's a fairly common prank to add bunches of
     newsgroups whose descriptions spell something out. Ask your local
     news adminstrator to remove the whole lot.
  4.9) Hey, one of those net.cops posted an ad for {something}! Haw! Haw!
     "Ad" does not equal "spam".
     "Ad" does not equal "net-abuse".

  news.admin.net-abuse.misc charter:
     news.admin.net-abuse.misc is for the discussion of possible abuses
     of netnews and e-mail. It is for the discussion of standards of net
     abuse, to suggest appropriate courses of action (if any) to net
     abuse and to post reports of alleged occurrences of net abuse.
     Relevant topics include events associated with net abuse such as:
     spamming (posting many individual copies of any article), excessive
     crossposting of non-germane articles, injection of malformed
     articles into the news system (broken gateways, for example), or
     other forms of "roboposting" involving large numbers of postings to
     one or more groups, forging identity of postings, forged approval

     news.admin.net-abuse.announce Charter and Guidelines
    1. What topics are relevant to this group? Events associated with net
       abuse, such as:
          + posting many individual copies of any article.
       Or, excessive crossposting of non-germane articles.
          + injection of malformed articles into the news system (broken
            gateways, for example), or other forms of "roboposting"
            involving large numbers of postings to one or more groups.
          + Forging identity of postings
          + Forged approval to moderated groups
          + Forged cancellation of articles not included above. Note that
            cancellation of net abuse articles is also relevant to the
            topic of net abuse.
          + Use of rmgroup/newgroup in an abusive manner
          + large-scale mailings to mailing lists or other mail-bombing
       Postings to this group may also include announcements relevant to
       the topic of net abuse, such as news reports, reviews, and
       conferences, and possible net-abuse FAQs.
       The purpose of this group is not to decide the guilt or innocence
       of any parties, but rather to simply report on the activity (much
       like the crime section found in many local newspapers). It must be
       kept clear that the net is a new legal area, but it is also one
       with a lot of unwritten rules. The moderators are in no way are
       attempting to act as judges, lawyers, or mediators.
    2. Posting of reports of this kind of activity in no way implies that
       net-wide cancellation of such articles are to be encouraged. How
       local news admins deal with such incidents is strictly up to them.
       The moderators of this group should not be held responsible for
       actions taken by others in response to articles posted to
    3. No moderator will engage in the following activities:
          + cancellation of any posts other than ones posted by them,
            excepting articles with forged approval to newsgroups they
            moderate or, if they are a news admin, posts originating from
            their site (following the local site's procedures).
          + Sending of "mailbombs", threats, abusive e-mail, or other
            attacks in response to alleged net abuse.
    4. We are committed to providing accurate information regarding
       events related to net abuse (with emphasis on Usenet) in a timely
       manner. However, as we the moderators must often rely on the
       reports of others, whenever we have not confirmed a report
       ourselves we will state so in the posting.
    5. Right of Reply. If posts have been made in this group concerning
       an individual's alleged net abuse and the individual and/or site
       from which it originated have suffered negative consequences in
       the form of articles cancelled, accounts cancelled, or substantial
       negative email; then the individual and site each have the right
       to one (but no more than one) reply for the purpose of
       justification, rebuttal, or reports of actions taken to correct or
       cancel the alleged abuse.
    6. Examples of inappropriate postings:
          + redundant reports of events
          + Trivial events, for example "Hey, this guy posted an ad to
    7. Administravia
          + Approval of postings will be made by a team of moderators.
          + Change of moderators will be made by majority. Forcible
            removal of a moderator will be by consensus of remaining
          + Any rule changes will be made by majority of the moderators.
