Facebook fact checkers did not know they could vet adverts
Many third-party contractors learned of new policy from Mark Zuckerberg’s testimony to Congress
Many of Facebook’s third-party fact checkers have still not been told that the company now expects them to vet adverts as well as user content for misinformation – though, controversially, not political adverts.
Some fact checkers only found out that they should be vetting paid adverts after Facebook chief executive Mark Zuckerberg described the new policyin Congress on Wednesday.
