Facebook is beefing up its attack on fake news by targeting coordinated campaigns aiming to use false information to sway political opinions on the social network.

Facebook has evolved into a forum for political debate in recent years, but some organizations have used the network to distort political sentiment for a specific geopolitical outcome, including during the recent elections in the US and France, Facebook said Thursday in a white paper (PDF). The social media giant said it has a responsibility to keep its community safe for authentic civic engagement, free from the influences of what it calls “information operations.”

Facebook explained, “We have had to expand our security focus from traditional abusive behaviour, such as account hacking, malware, spam and financial scams, to include more subtle and insidious forms of misuse, including attempts to manipulate civic discourse and deceive people.”
