Well, he's already been banned twice in the past, but his need for attention is so great and his intellect so small (nonexistent really) that he just doesn't have a clue that no one wants him here. It's the only contact he has with human beings where they won't just kick his azz for being such a putz if he doesn't go away.
However, since he HAS been banned from here at least twice, why HAVEN'T the mods booted him yet?
