From my experience, someone knew of you and thought you'd make for a good admin, so they promoted you. That the wiki was closed so quickly is often due to the founder ban evading and getting shut down real fast, which often will include the new wiki being shut down with them.

As mentioned, you have no worries. However, if you know of a user/anon who contacts you with a "hey, it's me, [blocked user]", consider if you want to be associated with them at all.
