Fake news and disturbing content

Another issue faced by Facebook and their acquired messaging service, WhatsApp, was the issue of fake news or misleading news. Also, adding to the degradation of user experience was the presence of visually and/or emotionally disturbing content on the platform. And finally, there was something that nearly all online platforms had to fight: spam. Facebook's AI algorithms over the years have become very good at identifying and removing spam. By the application of computer vision solutions facilitated by the usage of CNNs, Facebook has been able to come up with a feature that covers/blurs visually disturbing images and videos and asks for user consent before allowing users to view them. 

Work on identifying and taking down fake news is currently under progress and is almost entirely being done by the application of AI.
