Snapchat is tightening up its guidelines for publishers on its Discover service, banning the posting of risque images without editorial value, and clarifying guidelines intended to prevent the spread of fake news on the platform.The changes, according to a spokeswoman for Snap, Snapchat’s parent company, are intended to “empower our editorial partners to do their part to keep Snapchat an informative, factual and safe environment for everyone”.Toeing the line between keeping Snapchat age appropriate for younger users – the app bars children from under 13 from making accounts, but allows 13- to 17-year-olds on the service – and allowing publications on Discover editorial freedom has been difficult for the company, particularly when media organisations know one way to appeal to the app’s millennial user base is with prominent use of risqué images.The Daily Mail, for instance, has attracted user complaints for frequently posting semi-nude images as its “cover” on the service. “I find it incredibly offensive that I can’t opt out of seeing these images and that I am forced to see these images every time I open up the app to see my friends’ stories,” one user told the Guardian. “Usually, I just put up with it, but a few weeks ago, a definite line was crossed”, she said: “The image was of a completely nude female on the top … The picture was taken from the side, so you can’t see the nipples but her breasts were dangling over her boyfriend who she was mounting. She was dressed on the bottom and I believe her boyfriend was completely dressed.”Due to the prominence of Discover features in Snapchat’s app, the cover story is visible even to users who simply use the service to talk with friends and family. In July 2016, Snapchat faced a lawsuit over sexualised Discover stories. It was eventually settled out of court.Snapchat’s new rules will require some news justification or other editorial value before such stories can be posted to the service. Snap also plans to give publishers a tool in February that will allow them to age-gate content, presenting different stories to users over and under 18, according to the New York Times.Snapchat cracks down on risque images and fake news.
