FACEBOOK has removed 652 pages designed to meddle in the US mid-term elections.
The social media giant claims the pages come from Iran and Russia, and were operating a “coordinated political influence operation”.
Mark Zuckerberg’s company released a statement saying the pages were designed to mislead users.
“We ban this kind of behavior because we want people to be able to trust the connections they make on Facebook,” the statement read.
“And while we’re making progress rooting out this abuse, as we’ve said before, it’s an ongoing challenge because the people responsible are determined and well funded.”
In two cases, Facebook’s head of cybersecurity policy said they tracked campaigns called Liberty Front Press and Quest 4 Truth back to Iranian state media.
The campaigns were followed by hundreds of thousands of people.
Russian campaigns were linked to the Kremlin’s military intelligence unit and focused on information about Syria and Ukraine, spreading pro-Russia and pro-Assad content, Facebook said.
Earlier we revealed how Facebook is rating users based on how “trustworthy” it thinks they are.
Users receive a score on a scale from zero to one that determines if they have a good or bad reputation – but it’s completely hidden.

The rating system was revealed in a report by the Washington Post – and later confirmed by Facebook to The Sun – which says it’s in place to “help identify malicious actors”.
Facebook tracks your behaviour across its site and uses that info to assign you a rating.
Last month Facebook uncovered “sophisticated” efforts, possibly linked to Russia, to influence US politics on its platforms.
