reddit has been coming down hard on vpn users since last year. its futile one they shadowban you, rarely i see peoples ban get lifted on the shadowban sub, apparently and pretty obvious, The user said reddit "made a mistake because thier filters were misconstruing your words for somethng offensive", i doubt reddit admins have time to look at every appeal, thats why i believe they ignore most of them, if not all accounts that are part of the multiple accounts from a single users.
