I thought I'd chime in here as well. This guy has also shown up at Rebelscum's forums. His ID (that we know of) is ImperialRTS & the e-mail is the same as the ID he's using over here.
Something about this name & some of these e-mail addys seems very familiar, I just can't put my finger on it. But I'm sure there's been a warning about this guy in the past. If I recall anything, I'll be sure to post it here as well.
