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.
It’s only there because there’s some odd contradiction between the first and second part; someone who considers the existence of Reddit “sad” wouldn’t be expected to be there. @Sylvartas@lemmy.dbzer0.com’s reasoning is in the right direction, with the “something shameful” being “to be in Reddit”.
That said I’m a bit too prone to spam discourse markers like this. Or like “that said”.
