Plz note their is a % of a BAN but it's SAMLL just keep it need to no besic, meaning dont go around say i MOD THIS AND THAT that's how most peps get's the HAMMER.
You can't really give a percentage estimate on being banned. If it happens, it happens. You take the risk. Don't wanna be banned? then stay clear of it. However use precautions, patch games, don't play early. Don't mod online in public games or go around telling people that you are modding the game as Shadow said.
ive been modding for ages and ive been banned 7 times but never my profile its always been a console ban so yes theres a chance you can get banned
