I don't understand why someone can't use the same name as someone else, there is a ton of inactive BLID's that are just sitting there taking names.
Badspot should unlock the use of already used names, just add name history in the Player list and have BLID's enabled by default in the Player list again.
Steam doesn't block the use of same usernames, and there isn't an issue, there is also a Name history in the account page of a person.
