I'd just like to say that we already have a block option for "unacceptable username".

Meaning you guys recognize that yes, these do exist. Even if the signing in and of itself was okay, this WILL result in pages on G or PG-rated wikis having "This image uploaded by cocksucker prime", or whatever the format is you're using. And, because of that whole ethics thing, we can't delete or remove a perfectly acceptable image just because we don't like their name.
