If you create a Custom Game that in any way encourages players to gain experience while inactive, you risk having your account banned. If you join any game mode – including Custom Games – with the intent of gaining experience while being inactive, you risk having your account banned. Also, do not name your Custom Game that in anyway even implies that gaining experience while inactive is OK – please do not even do this as a joke – because you are putting yourself at risk of having your account banned.
