Speaking for myself, the problem here are the off-topic posters and no

Actually, you might find that many of these off-topic posters are
posting to multiple newsgroups. A decent newsreader will let you
killfile by regular expression, so you can block, say,
Newsgroups: *,*,*
....which will block anything crossposted to 3 or more groups (like
Cliff's Crap). Amazing how much of the crap that takes out. And as DoN
stated, (paraphrasing), blocking entire continents by IP range, is quite
effective as well.
