It looks like Facebook's problem with fake news has kicked off a war inside the tech firm.
Buzzfeed News is reporting that "more than dozens" of staff have created an unofficial task force to sort out the problem.
The key issue is that it's not always immediately obvious which news isn't real.
"It's difficult for people scrolling through Facebook quickly, often on small mobile screens, to get a sense of what's real and what isn't," says Claire Wardle, from the Tow Center for Digital Journalism.
