Bans are manually placed on accounts following account investigation that turns up behaviour that justifies the action being taken. These investigations can be started by multiple reports of cheating or otherwise disallowed behaviour over a long time period. Alternatively, bans may be placed after the Destiny 2 app on PC detects potential cheat software and flags it, sending data to Bungie - again requiring manual confirmation for a ban to be placed. The only other way to obtain a ban is to continue to play match made PVP and gambit, following both a 2 week and 2 month restriction from those activities. In all seriousness, and with respect, Bungie has found reasonable evidence that you have broken the Destiny code of conduct in some way and been appropriately punished for it. There is no way to appeal a ban or have it overturned. Bungie does not discuss or revoke restrictions or bans. Your only chance of a definitive explanation is if BNGSecurity replies to your post here, and even that’ll only happen if and when they feel like it.
