Have you checked whether the IP and emails are also blocked? See:

I've accidentally "blocked a spammer". Any way to unblock their IP?

So yeah, this is embarassing. In the process of trying to delete an old account that wouldn’t delete for some reason (that’s an issue for later), I ended up deleting the wrong account. Basically the user had two accounts, wanted the first one deleted, and after changing ownership of their one old post I accidentally went and attempted to “delete spammer” out of desperation, forgetting that I’d changed the ownership and deleted the wrong account. Yeah, I’m an idiot… But I go to the blocked list …
