Facebook revises guidelines over banned content

Social media network clarifies its stance on nudity, self-harm, terrorist threats, violence, graphic content

Facebook has created a rule book that tells users the sort of content they can and cannot post on the site, including a ban on images of buttocks.

The social network has been criticised in the past for inconsistency when it comes to user-published content. While images of breast- feeding have been tightly clamped down on, videos of beheadings have made it onto newsfeeds on more than one occasion.
