I don't know what words.
I'm hoping relay operators have a clue and can tell me what words I need to censor, and how bad of a person I am for using them, so I can comply like a good little boy. ;-) Or maybe I'll just switch to different relays. I bet you can guess which one of those two choices I'm going to go with.
If it is a bug or a false positive, the relay people should know so they can fix it.
