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.
Got shadow banned years ago for sharing the link to the εxodus privacy analysis of the Reddit app. There is a reason why they keep trying to pressure their users to use their app. It's farming their personal data.
It is a great resource to know what an app is doing behind your back
a dedicated anti-detect browsers eliminates reddit from identifying you, for the most part(plus if you use proxies as well)
