Isn't going to happen. Don't forget that the users on this board are linked to the licenses and are only created by the software that handles accounts (you can't register here on the forums). If you were to change the forum name, you'd have to change the license name, too. The problem with that is that the name is I think de-facto the primary key for identifying licenses, so all LFSW stats or uploads and all info servers stored about you (bans...) would be invalid or broken.
I'm sure it is technically possible to change the name, but it would be a huge hassle and require lots of extra coding and messing around (create a new account, transfer the funds, delete the old account, update all references to the old account everywhere to now point to the new one, etc. and the bans issue still wouldn't be solved). If they ever made an exception and did it for one person, you could be sure tons of people would instantly demand a namechange, too, so they won't even start with that. Also they'd admit that their rules ("you cannot change your username after the registration - your username is permanent!") can be circumvented anyway.
