Here is what The makers are hoping for. People that will hack it, so they can generate list to ban players from their game servers. This would not mean a username account, this would mean a PS3 ban of the particular console from the game itself. This does not mean from PS3 online gaming, but just from the servers of that game. This would make all of your legit accounts go offline too for that game.
Each PS3 has its own code incrypted, so its easy really for them to identfy, and ban from a game server.
Its coming sooner than most think.................
