Facebook has faced scrutiny for not taking more action against fake news and misinformation, including interference by Russian trolls during the 2016 US presidential election. Last year, the social network landed in hot water after it was revealed that Cambridge Analytica, a digital consultancy linked to the Trump presidential campaign, improperly accessed data from as many as 87 million Facebook users.

"We value the work that Snopes has done, and respect their decision as an independent business," a Facebook spokesperson said. "Fighting misinformation takes a multi-pronged approach from across the industry. We are committed to fighting this through many tactics, and the work that third-party fact-checkers do is a valued and important piece of this effort."
