OP I see you post these kinds of threads publicly regularly. These types of things shoudl really be handled via PM with moderation staff. PSForumMods is who you should send your concerns too, if reporting it doesn't meet the with results you expect.
PM'ing the mods hasn't done me any good either. Most of them don't even respond back and the others just tell be that the particular user is in the right and theres nothing they can do about it.
Gee, I remember how Jive Moderation always replied back! M_S, Sushi_Pirate and others.
