what words are not allowed on Brianly?

I can't even say the abreveation for "I don't know"
and some passages can't be put on here I'm guessing becasue of foreign names

I understand the secrecy is part of the profanity protection, but it's kinda frustrating to play "needle in a haystack" in a massive wall copy-pasted of text, and you don't even know what the "needle" looks like
