The European Commission has expressed its concerns after Facebook repeatedly withheld key data on its efforts to clamp down on disinformation ahead of the European Parliamentary elections. An upcoming EC report details that the social media giant has employed “fact checkers” tasked with scrutinising information shared on the site in only eight of the twenty-eight member states. EU sources have said that the sector was not raising its game and that Facebook was by far the worst offender of those being assessed, offering only “patchy” information on its efforts.
