If a story is deemed false, it will be tagged with an alert message saying it's been "disputed by 3rd party fact-checkers." In a news release outlining how Facebook's new reporting and flagging process will work, Mosseri said the company will rely on its users to report a story as potentially bogus, "along with other signals." "If the fact-checking organizations identify a story as fake," Mosseri said, "it will get flagged as disputed and there will be a link to the corresponding article explaining why. And the disputed stories "may also appear lower" in the algorithmic News Feed that appears on the Facebook home page. Mosseri added, "It will still be possible to share these stories, but you will see a warning that the story has been disputed as you share."
– Facebook on Thursday announced a concrete step toward combating the spread of fake news. NPR reports Facebook will allow users to flag stories they believe to be fake. Those stories will then be forwarded on to one of several fact-checking organizations that have signed on to Poynter's International Fact Checking Code of Principles, according to CNN. (Facebook won't be fact-checking stories itself.) If the fact-checker decides the story is false, it will be labeled "disputed by 3rd Party Fact-Checkers" on Facebook. Users will still be able to share the story but won't be able to turn it into a promoted ad. Facebook says a lot of fake news is being created to make money, and hopefully this will help fight that. Disputed stories may also be placed lower in the News Feed.
