@Kabam Miike Regarding people who cheat to win in battlegrounds, Why don't you instead of banning, just restrict them to go forward (but this will require frequent checkings to happen during the season i mean like you take time to remove cheaters manually). Let them play other modes but restrict in the mode in which he/she used cheat.
Punishments to be like,
Modding - restrict till the season gets over.
Not accepting battle beyond certain limits - restrict for a day or some hours.
Also in order to stop raged people who receive restriction, keep higher level eligibility for newly opened account which is less than a month old.
Thank you
