Russia continues to be the top creator of disinformation on social media, with the country hosting the most fraudulent and misleading Facebook accounts, according to a new report.

report from Facebook reveals the social media company has discovered misinformation efforts in more than 50 countries since 2017 - with Russia being the biggest source of "coordinated inauthentic behavior" with 27 bogus networks identified.

Between 2017 and the end of 2020, Facebook says it took down 150 networks of fake accounts - many of them foreign disinformation campaigns aimed at influencing Americans and others founded in the U.S. by local extremists. Facebook says it has 2.85 billion users around the world.
