not the only one, i was part of the ban/purges of febuarary, and some of 5+years got hit. 1 was currently suspended(i accidentally deleted) suddenly all my accts were hit with bans at once, around the same time the all the subs had increased thier spam filtering, and threshold to comment, apparently it immediately flags your acc as spam, if your comment gets autoremoved. there has been at least 3 big ban purges since nov of accounts. apparently they will get you if you made an acct years ago and then banned from a sub, but they decided to make a new account and forget it about it years later, and accidentally commented in said sub, your accounts get targeted. punishing redditors for accounts they deleted and forgot more than a year+ ago, is something new.
