EDIT: @[email protected] 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.
another way to check, is while logged out and in private mode, you search up your account name to see if its suspended, or it doesnt exist.
