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 the general notice from reddit, when they ban all your accs at once, even old ones you stopped using. its a bot doing it. i had like multiple accounts, each one for a specific niche, or sub, including throwaways, those in the niche subs(never gone on political or news subs) still got targeted. its mostly like whatisthisplant, or this medical issue.
