NoCeM
=====

   "Spamming" is posting the same article lots and lots of times.
Spamming is bad.  Spamming is evil.

   Spamming is usually canceled within a day or so by various
anti-spamming agencies.  These agencies usually also send out "NoCeM"
messages.  NoCeM is pronounced "no see-'em", and means what the name
implies--these are messages that make the offending articles, like, go
away.

   What use are these NoCeM messages if the articles are canceled
anyway?  Some sites do not honor cancel messages and some sites just
honor cancels from a select few people.  Then you may wish to make use
of the NoCeM messages, which are distributed in the `alt.nocem.misc'
newsgroup.

   Gnus can read and parse the messages in this group automatically, and
this will make spam disappear.

   There are some variables to customize, of course:

`gnus-use-nocem'
     Set this variable to `t' to set the ball rolling.  It is `nil' by
     default.

`gnus-nocem-groups'
     Gnus will look for NoCeM messages in the groups in this list.  The
     default is `("alt.nocem.misc" "news.admin.net-abuse.announce")'.

`gnus-nocem-issuers'
     There are many people issuing NoCeM messages.  This list says what
     people you want to listen to.  The default is `("Automoose-1"
     "clewis@ferret.ocunix.on.ca;" "jem@xpat.com;"
     "red@redpoll.mrfs.oh.us (Richard E. Depew)")'; fine, upstanding
     citizens all of them.

     Known despammers that you can put in this list include:

    `clewis@ferret.ocunix.on.ca;'
          Chris Lewis--Major Canadian despammer who has probably
          canceled more usenet abuse than anybody else.

    `Automoose-1'
          The CancelMoose[tm] on autopilot.  The CancelMoose[tm] is
          reputed to be Norwegian, and was the person(s) who invented
          NoCeM.

    `jem@xpat.com;'
          Jem--Korean despammer who is getting very busy these days.

    `red@redpoll.mrfs.oh.us (Richard E. Depew)'
          Richard E. Depew--lone American despammer.  He mostly cancels
          binary postings to non-binary groups and removes spews
          (regurgitated articles).

     You do not have to heed NoCeM messages from all these people--just
     the ones you want to listen to.

`gnus-nocem-directory'
     This is where Gnus will store its NoCeM cache files.  The default
     is `~/News/NoCeM/'.

`gnus-nocem-expiry-wait'
     The number of days before removing old NoCeM entries from the
     cache.  The default is 15.  If you make it shorter Gnus will be
     faster, but you might then see old spam.
