The New York Times highlights the case of Comet Ping Pong, a pizzeria based in Washington, D.C., that was the subject of several fake news stories online.

These stories falsely alleged that the restaurant was a hub for child trafficking after Comet was mentioned in the hacked emails from Hillary Clinton campaign chairman John Podesta that were released by WikiLeaks.

As the Times reports, “The articles appeared on Facebook and on websites such as The New Nationalist and The Vigilant Citizen, with one headline blaring: ‘Pizzagate: How 4Chan Uncovered the Sick World of Washington’s Occult Elite.’”

As a result, the owner of the restaurant and the staff started receiving a torrent of threats via social media, including one message that said, “I will kill you personally.”

After Media Matters launched a petition asking Facebook to take action to address the rampant problem of fake news circulated via its service, CEO Mark Zuckerberg has publicly committed to working on the problem at the social media giant.
