Facebook has removed more than 650 Facebook and Instagram pages, groups and accounts originating in Iran and Russia for "coordinated inauthentic behavior." The goal is to improve the trustworthiness of Facebook connections. Although it has been making progress in its efforts, the people responsible for the inauthentic activity are determined and well funded, Facebook said. "We identified an influence operation, not just on Facebook, but across several social media platforms," said Sandra Joyce, vice president for global intelligence at FireEye.
