Is there any way, or any recourse to stop a usenet (via google) harrasser
who is ruining several usenet groups? He makes it impossible to carry on
on-topic discussions as he purposely sabotages them with his bull crap
harassment of women posters. And he will latch onto a women poster and
follow her to each newsgroup she goes to and post the same crap and lies
and
harassment about her. What can someone do? If you killfile him that
only
blocks an initial post. There is always someone new that responds to his
bull.

We know who you mean. He needs to be committed to the VA Hospital and put
back on meds.
