Yes, as Tippiechick and MysticCat said, the posts get deleted. For that same reason, it's not wise for people to repost their content, as the reposts will likely get deleted too. Shortly after his most recent ban there was a thread up that repeated some of the things he had said, speculating that they were the cause of the ban. That thread was deleted shortly thereafter.
This thread is heading that direction, too, I'll bet.
I used to want to think that he was being picked on for no reason, I really did. His actions have proven to me time and again that I was an idiot to have ever held that belief.
