The Federal Agency of News (FAN) has accused Facebook of acting in concert with the US Justice Department (DOJ) to "rid the platform of Russian language accounts," and says it was inappropriately linked to the Internet Research Agency (IRA) - as the two companies shared a building between 2014 and 2015. 

FAN's US-focused website, USAReally.com, has also been blocked on Facebook, Google and Twitter - which the company says is part of a "witch hunt" against Russians. 

IRA was one of three businesses and 13 individuals indicted by Robert Mueller in February for alleged meddling in the 2016 US election for allegedly facilitating a "troll farm" operation designed to influence the 2016 US election. FAN's founder, Alexandra Yurievna Krylova was indicted by Mueller in February for her work at IRA between September 2013 and November 2014.
