I propose that a player can only change name if it generates a normal name change history that can be searched on the username change utility. If a player can't do this , then they should keep one name per cpu for the entire time on FAF. Doing otherwise should be considered exploiting the system and administrative action should be taken.
I also propose that a feature be added to the game lobby to turn live replay off by the game host.
Finally, I propose that you add a mute feature like GPG that not only mutes a marked player's chat in lobby but also keeps them from joining a game lobby that you are in. (I understand this is difficult to implement)
