EDIT: @mindbleach@sh.itjust.works shared something that might help to circumvent this shit:
Contained in these parentheses is a zero-width joiner: ()
Basically, add those to whatever you feel that might be filtered out, then remove the parentheses. The content inside the parentheses is invisible, but it screws with regex rules.
thats actually new thing to me, i have seen alot of the famous subs have upped thier filters, i avoid them by filtering out those subs from my feed. also people might make a mistake by accidentally commenting on the sub they were ban years ago, apparently the filters doesnt discrminate or clear itself once your bans are lifted or years old.
It's suck, but if you make reddit account again, wait for around 3 month, or 1 year just to safe before comment. Or you can comment on smaller subreddit but don't make post. Just comment
Subreddit like r/linux shadowban you if you make post if your account too new
may have to try that. i was in a forum, where people are create tons/buying of accs at once and trying to comment in less than 1 week, i was thinking these people should chill especially with the bans going on(and these are the OF accs, using evasion methods) and your making things worst by increasing reddits filter sensitivity to bots and people that are flying under the radar are getting caught as well(these people who are using more advanced techniques to evade bans have 50+accs). i am aware of several subs that will ban/remove comments you asap if your karma and acc age isnt high enough.
