Snopes, a fact-checking organization, announced on Friday its decision to end its partnership with Facebook, which has been ramping its efforts to curb misinformation on its services since the 2016 U.S. election.

Facebook and Snopes had been working together since December 2016 to fact check content on the social network. The company in 2017 paid Snopes as much as $100,000 for the work, according to Snopes.
