If the server's reform is successful, I strongly recommend you just keep Crepe banned and ignore what he says. I have had some nasty experiences with Crepe myself, and from it I can say this:
Do not be fooled by his seemingly innocent pleas for unbanning. He can be convincing, but you've seen what he likes to do with it.
I hope that the server/project can come back on top of things again, and if so I'll continue to do my best to contribute.
