Facebook released its "Community Standards" on Tuesday, a list of official rules that outlines the types of posts that can get you banned from using Facebook. It also outlines the types of users it doesn't allow to post.
I dug through Facebook's guidelines to understand what's allowed and what isn't.
Summary:
Violence and Criminal Behavior
Safety
Objectionable Content
Integrity and Authenticity
