The Guardian: Facebook promised to tackle fake news. But the evidence shows it’s not working . “Articles formally debunked by Facebook’s fact-checking partners – including the Associated Press, Snopes, ABC News and PolitiFact – frequently remain on the site without the ‘disputed’ tag warning users about the content. And when fake news stories do get branded as potentially false, the label often comes after the story has already gone viral and the damage has been done. Even in those cases, it’s unclear to what extent the flag actually limits the spread of propaganda.”
