As other people have said, there's no need to keep these names blacklisted. There are problems with the black list though, namely that there are so many spammers that if you every wanted to black list an actual player you'd have to remember their name and be sure not to delete them from the list. We also need some sort of mass removal system for out black lists. Again, something more than just delete all (which would work for me and a lot of others) since you theoretically do want to keep some players on the list.
