Snopes quits Facebook's factchecking program amid questions over its impact

News site says it wants to ensure its efforts are a 'net positive' for community, as some journalists doubt program's effectiveness

Facebook's controversial factchecking program has lost one of its major US partners. The news website Snopes.com announced on Friday it was cutting ties with the social network.

The departure of Snopes, which has collaborated with Facebook for two years to debunk misinformation on the platform, doesn't come as a surprise. Numerous journalists working for Facebook's factchecking initiative have said the partnership was failing to have an impact.
