Gamer Warning: Promoting hacks will be punished as severely has hacking itself.

Hack programs modify your game permanently and can promote hacks without you knowing it. This includes room names. You will be banned/suspended if caught for creating a room name that promotes hacking as this implies that you hack yourself.

You have been warned.

But for example if a hacker creates such a room and he is kicked from it, someone else will be the host if the room.Thus could be unfair to innocent players.

thanks for telling us
