Facebook has just updated its guidelines on what posts and images users can expect to get banned from their site, including a list of nudity that will be deleted and an entire section on ‘dangerous organisations’. The new guidelines aim to provide more detail on what the site administration will ban on Facebook, with explicit updates naming "fully exposed buttocks" and "images of female breasts if they include the nipple" included in the new content shutdown. The ban includes computer generated image nudity, as well as text that describe sexual acts in ‘vivid detail’. The new content regulation will also see a permanent ban to any users who attempt to post revenge porn on site. Tackling the ongoing issue of breastfeeding images, Facebook’s new guidelines will allow pictures of breastfeeding women, or images "showing breasts with post-mastectomy scarring". Images of paintings, sculptures or art depicting nudity will also be allowed. While most welcome the new guidelines, and the review of breastfeeding bans, others have noted no update to the rules regarding streaming violent content or graphic images. Instead, Facebook has advised users to warn audience members that updates could include graphic violence, but the videos will continue to play automatically in timelines. Facebook's new rules also have special sections for criminal activity, self-injury and bullying, all of which it says it will do more to remove.
