No guidance or policy regarding prohibited words.

I was "warned" that my review would rejected for "Prohibited words," and I needed to edit it. The review did not contain any 4-letter words. So I did some research to figure out if there was some sort of policy or guidelines. All I found were dozens of people posting the same question over and over again. "How am I supposed too know which words are prohibited?" So why isn't there a list of prohibited words or any guidance at all? That's crazy stupid. It is unacceptable.
