Unban Larry?

Should we? Larry and his stupidness almost caused the downfall of Entmoot before it had really even begun, and banning was the only real option at the time. He is currently IP banned. Just now he asked to be unbanned. I'm not sure if we should or not. He promises to behave, but can we trust that? Back in the "old days," it didn't really matter what went on since no one ever visited anyway :P. Still, it was important to me to keep the board civilized, and Larry was disrupting everything. But now he claims he'll post (semi-)intelligent posts. What do you think, should we give him another chance or what?
