AI bans dont tell you that your what you were banned for, its always the generic "you have violated mutliple violations, on your ACCOUNTS" message. they also use AI moderation to shadowban people too, which i think is much more severe than the sitewide banning. they originally shadowban people for using ban evasion accounts, but now they are abusing to ban anyone indiscirminately(aside from a selected group of users).

i think reddit also gatekeep new users, and inactive users.
