I'm not sure if that which I describe below is what Greg had in mind, but
there are "spambots" that automatically delete articles. How they work
is much tied into how the NNTP (Usenet) protocol works.
When a spambot detects an article that matches a keyword in a "delete"
list, it sends an cancel-article for the message-id of the offending
article to a newsgroup called "control". When this cancel-article
propagates to other sites (every Usenet site MUST carry the newsgroup
"control"), they will expire or delete the article in question from their
news-spool.
This mechanism is actively used at several sites to control spam posts
to many non-bionet newsgroups. I do not know the legality of running
a spambot for a bionet newsgroup and am hence reluctant to run one
myself, or offer the resources to run one from.
I principle, I concur that a bionet-spambot would be wonderful.
