I still like the old Netscape 4.78 mail and news reader software, AKA
Netscape Communicator, 4.78.

You can create kill filters per newsgroup, or install Newsproxy to
filter the losers from every newsgroup you read.

I liked 4.78 too but had to migrate to 7.2 for browser features.
How did you get the filters to do useful work for newsgroups?
The filters in 7.2 only work on 'sender' (not a canonical field),
'subject' and 'date' headers and are essentially useless for
the current state of affairs.
