[Air-L] Asking for help about Facebook censorship criteria.

Dear listers: I´m looking for information about the criteria that Facebook uses to take down some "incorrect" pictures, photos, images. I know something simple as the "niple rule" -not images allowed showing women niples- wich generated reaction from women feeding their babies... Can you help me? Greetings from Argentina!
