If a user hasn't made any edits on a wiki, and they request a username change, and gets approved, which it always does unless there's a very good reason not to approve it, then the original username will remain blocked, but the new username will not be blocked, so the user will implicitly have evaded the block placed on their account, whether it be intentional or otherwise. I've experienced this problem with at least two users that created sock-puppets, one of which was a cross wiki vandal and troll.
