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.
What the fuck is a Reddit?
Some really shitty site. Going downhill day by day. To the point even your typical user is looking for alternatives.
Sounds really complicated who wants to use that trash!
