Does fluther have guidelines for questions and answers and did the Mods exercise a stricter interpretation of those guidelines a year ago?

This question was sparked by the diatribes present in another. And by watching the types of answers that are allowed to remain without editing on some of the most controversial posts.

So, if fluther has guidelines for questions and answers, then have the Mods backed off on their interpretations of those guidelines? Or am I missing much valuable information because many flutherites chose to PM each other rather than hang out in the chat room to discuss the problem or actually flag offensive commentary when it shows up in a post?

Or are there no guidelines for answers?
