evidence: Facebook started partnering with third-party fact-checkers in December 2016, in the wake of the US elections which saw disinformation widely strewn across the platform. Now Full Fact's team of six fact-checkers – who will work on Facebook alongside their other responsibilities – will be able to review stories, images and videos posted on Facebook and rate them as true, false or a blend of fact and inaccuracy. [...] It will be up to Full Fact, though, to choose what particular posts to assess, as Facebook will have no say on either what claims Full Fact reviews or the content of its fact-checks. "Factchecking is slow, careful work — so realistically we're not going to be able to factcheck everything that appears on Facebook," Bamber explains. [...] This project will be funded by Facebook as part of the firm's third-party factchecking initiative. The funding, Bamber confirmed, will be dependent on how many pieces of content Full Fact checks. Facebook and Full Fact had previously collaborated on a one-off project in 2017, when Full Fact produced a decalogue of tips to spot "fake news" Facebook subsequently promoted on users’ newsfeeds.
