I believe that was related to the second ban, not the original one. But I wasn't a mod during the original set of incidents, just a poster.
I just dug up the thread on the mod board discussing the original ban in 2007, and it involves a thread in which Jamespol calls Alcon a "dumbfock" and tells Straha "go f*** yourself b**ch". He was also said to PM people things like "GO TO HELL YOU BASTARD TEXASINDY AND I HATE YOU". That's described as "the last straw" by the mods at the time, and Dave then banned him. There were subsequent returns that also led to re-bannings.
That thread also talks about him lying about Jake sending him porn? I wasn't really involved in the "community" side of the forum at that time, so don't really know what that's about.
