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.
Earlier this week, Facebook said it was going to do more to tackle the problem of made-up news, some of it intended as comedy, which people then shared.
Facebook founder Mark Zuckerberg said "only a very small amount is fake news and hoaxes" and denied Facebook played a role in Donald Trump's surprise election victory. "The idea that fake news on Facebook influenced the election in any way is a pretty crazy idea," he said.
One of the main news sites publishing spoof stories says it's actually providing a service.
"The world in 2016 is a messed-up place in a number of ways, and for many people carefully-constructed fake news is actually preferable to some of the utter garbage that is churned out by the mainstream news websites," Southend News Network wrote in an open letter.
Its "About" section states that it has "no real aims or objectives in mind other than to add a satirical/spoof-like touch to issues that people are passionate about.
