I was going to post a bull-shit responce like I did when someone asked about the stars under your name, but I won't.

They either have their I.P. E-mail, or username banned (blocked) from getting on (they still can just erase cookies etc) but they can't post under that name. They don't lose anything, they still keep theirs post counts, threads, posts, signature, and any information stored. Unless the admin actually deletes the account.
