One of more words violate Firefly user guidelines - huh?

A) It doesn't say which word triggered this, which is an issue especially if we're spending time writing longer prompts. 

B) We can only guess that the word mannequin is censored, I have to ask why? We use these every day with clothing...

C) What's the alternative? Is there a list of words that we can see that violate Firefly's guidelines so we can avoid these? Very little information is given with this issue...
