Now the social network is hoping to put an end to the confusion over what is and isn’t allowed to be posted with a 2,500-word online guidebook. Here are some of the key clarifications.

:: Nudity

Banned: Explicit images of sexual intercourse, images of genitals, “fully exposed buttocks”, digitally created nudity, and descriptions of sexual acts “that go into vivid detail”.

Allowed: Photos of women “actively engaged” in breastfeeding, images of post-mastectomy scarring, photographs of art which depicts nude figures.

:: Hate Speech

Banned: Direct attacks on people based on their race, ethnicity, nationality, religion, gender, sexual orientation or disability. 

Allowed: The sharing of someone else’s hate speech “for the purpose of raising awareness or educating others about that hate speech”. Also allowed is “humour, satire or social commentary” related to hate speech topics if the user is posting under their real identity.

:: Violence And Graphic Content

Allowed: Such images if they are posted to “raise awareness” of human rights abuses, acts of terrorism, or another issue of public interest.

:: Self-Injury

Banned: Images or information promoting self-injury, eating disorders or suicide.

Allowed: Self-harm and suicide information which does not promote them is allowed. Body modification images are not considered self-injury by Facebook.

:: Direct Threats

Facebook says it evaluates threats based on their credibility – looking at things such as a person’s physical location.
