Facebook will now mark “fake news” as “disputed.”

Citing Facebook's Help Center, media reports say news stories that are reported as fake by people on Facebook may be reviewed by independent, third-party fact-checkers.  The fact-checkers will be signatories of the non-partisan Poynter Code of Principles.

A story will be marked as disputed if fact-checkers find the story to be fake.

To see why a story was marked fake, hover and click the dots under the disputed story.  Click “About Disputed Stories,” or go directly to the independent fact-checking website.

To mark a news story as fake, click the arrow next to the post you'd like to mark as fake.  Click “Report post.”  Click “It's a fake news story.”  Then click  “Mark this post as fake news.”

Facebook is an American for-profit corporation and online social media and social networking service based in Menlo Park, California.  The Facebook website was launched on February 4, 2004, by Mark Zuckerberg, along with fellow Harvard College students and roommates, Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes.  Facebook gradually added support for students at various other universities, and eventually to high school students as well.  Since 2006, anyone age 13 and older has been allowed to become a registered user of Facebook, though variations exist in the minimum age requirement, depending on applicable local laws.  The Facebook name comes from the face book directories often given to United States university students.

As of April 2016, Facebook was the most popular social networking site in the world, based on the number of active user accounts.  Facebook classifies users from the ages of 13 to 18 as minors and therefore sets their profiles to share content with friends only.
