NANA
 //

   [Usenet] The newsgroups news.admin.net-abuse.*, devoted to fighting
   {spam} and network abuse. Each individual newsgroup is often referred
   to by adding a letter to NANA. For example, NANAU would refer to
   news.admin.net-abuse.usenet.

   When spam began to be a serious problem around 1995, and a loose
   network of anti-spammers formed to combat it, spammers immediately
   accused them of being the {backbone cabal}, or the Cabal reborn.
   Though this was not true, spam-fighters ironically accepted the label
   and the tag line "There is No Cabal" reappeared (later, and now
   commonly, abbreviated to "TINC"). Nowadays "the Cabal" is generally
   understood to refer to the NANA regulars.
