Hey Allen I know it is pain when you get these kind of dweebs. But that
is part of the online experience whether in newsgroups or forums. I
think you should stay and keep contributing. Use filters, tools whatever
to cut down the noise level. Some day this low life will get his.

Twenty plus years ago there was somebody cross posting junk to almost
all of the newsgroups. A core of internet techies around the tracked him
down. They had some 'associates' have a 'face to face' with the idiot.
Gee, he never spammed the newsgroups again. So, one day this low life
will be tracked down and dealt with.
