One problem I have with this one is people do forge reports, and there
is no way around that.  Also, as long as there are networks that don't
enforce source address filtering, port probing complaints cannot be
validated (I take them as valid unless proven otherwise, but we have had
a few that appear after the fact to be forged and/or spoofed).  If you
_always_ take someone off-line on a single complaint, you make it easy
for someone to get someone else kicked off.

I don't speak for anybody but myself - that's enough trouble.
