Yeah I am a moderator although I am considered inactive (I just don't have much time these days to spend here). I apologize that I haven't responded sooner to this, but if it hasn't been resolved at this point I'll pass it along to one of the more active moderators.
Well, while it is upsetting to see a scammer on the forums, I cannot do anything in the PSU (360) forum. I mod the PSO, handhelds, and community forums. However, rather then reporting to me, click the "Report" button on said user's post and plead your case there. A moderator capable of handling the issues in that forum should respond.
