Perhaps they (myself included) would be helped by someone who can explain
this better. Some people don't even know how to find their killfile, no
less add filters to filter out the anon messages and messages from nym
shifters switching from Google to various NSPs etc. But then there are
different newsreaders out there to complicate matters.... you can see why a
troll well versed in "theocratic warfare strategy" feels they can kill any
NG with impunity.

Yes, but we really can't know how to filter your newsreader. Trick number
one is knowing how to see /all/ the header fields. In a support group that
I was involved in once, we had to block all the "free" mail host sites for
a while (yahoo, etc) to get rid of a particular troll. It worked.
