It wouldn't work like that. He account is truly deleted and cannot be recovered. However, if he created a new account I could re-join his previous posts to his new account.
If he did come and create another account I really don't think me or any of the mods would stop him
I doubt he would come back tbh...
He had his ego absolutely destroyed when he was banned, he genuinely thought he was immune so yeah, probably wouldn't come back.
