Again, I won't comment on individual words but those which was used in 2000s internets or those with proper dictionary definitions aren't b&, even if they are (still) a part of "modern slang". Heyuri is distinct enough from other western sites that we don't care about whatever existing words they abuse. We merely ban new words or non-dictionary meanings of old words they create. This applies more broadly than just words too, like ignoring lame Western fanbases of Japanese games etc.
