I have had a few reviews become deffered before they were posted. In one of the reviews I had posted that the girl was in Playboy. I think Staff just checked the providers website to make sure that she stated that she was in Playboy. The provider did state this and the review was approved later on.

What is meant by  "deferred?"

Sorry, I don't know what a "supervisor" is (sometimes AKA "the higher ups"), but that's what everone says.  Search under "deferred" (two Rs) for more (of the same) info.  Maybe if you go back far enough, you can get an answer to the second part of your question.
