1 game ban on record | Info

good thing there are more/other reasons then just cheating, to get a gameban.

Game Bans can be awarded for reasons other than cheating so it’s probably correct if it’s been more than a few days

Also, they are awarded with a time delay, so it could be a day a week or a month after the infraction
