Facebook is introducing tools designed to make it easier to report links shared in the News Feed as fake news, and itâ??s working with four independent fact-checking organizations to assess the accuracy of viral stories. Facebook users who try to share a story that has been marked as false will be warned that â??independent fact-checkers have disputed its accuracy.â??
