  Well, in this case and in what it concerns Esoterica, its spammers 0 -
isp -1

  We have a filter on incoming articles that not only detects ECP ( Excessive
 Crossposting) but also detects EMP (Excessive Multi Posting). By maintining
 a list of the last 5000 or 6000 articles, we can check using Subject,
Lines and
 From headers if there's a repetition of the same article being sent to
several
 newsgroups; if it is, we refuse the article. 

  Since we're a node of Usenet II, this is indeed mandatory for the net.*
hierarchy

  This filter is refusing something like 50000 articles per day.

  ( Does it show that I, as postmaster/newsmaster of Esoterica, have a thing
 with spammers ? I guess it does :-)

  C U!
