Facebook has launched a new function that will help mark fake news as “disputed”. The new tool will reportedly help identify websites and sources that are likely to put out misinformation. The social media giant’s tool uses fact-checkers like Politifact and Snope to identify fake news, Mashable reported.

Facebook has also added how to mark a story as “disputed”. A user can click on the right of the post and choose an option allowing them to mark it as fake news. Once the story is reported, it will be reviewed by third-party checkers that Facebook has teamed up with, like Poynter Institute, which is a media ethics organisation. However, it is not clear how many users or which Facebook users have access to this feature.

There has been widespread speculation that voters in the United States were swayed by fake news on social media that had pushed them to vote for Donald Trump. Facebook and Google had been accused of helping mislead voters by allowing misinformation to be spread by their websites. While Democratic presidential candidate Hillary Clinton had been ahead of Trump in popular votes, searches on Google after the election showed the opposite, owing to fake news generated by dubious websites.
