Yes, but the discussion on banning was sparked by his posting a new thread (now deleted) in which he cheerfully admitted to convincing a heroin addict to prostitute herself for him, and that he looked forward to doing it to other addicts someday. Regardless of whether discussions about illegal activities off the forum are banworthy in itself, it probably doesn't adhere to Dave's noble vision for his Atlas.
He also claimed himself to be a LaVeyan Satanist, which is a pretty good indicator that he's no older than the age of twelve.
In all seriousness though, his general behavior, to me, seemed to make a sufficient case for his re-banning. The prostitution story had a big role, no doubt, but it was pretty obvious the guy only came here to annoy everyone.
