Facebook updates nudity policy

No nipples or exposed buttocks on Facebook!

The social network has updated its "community standards" and has clarified its definition of nudity.

Pictures of genitals, fully exposed buttocks and female breasts, if they include the nipple, are not allowed.

If the woman is breastfeeding or showing post-mastectomy scars then that's OK.

Facebook also said so-called revenge porn, in which someone posts sexual images of another person without permission, is not allowed.

The company also followed up on its hate speech rules, saying attacks on race, ethnicity, national origin, religion, sexual orientation, gender and "serious" disabilities are banned.
