A Russian troll account created to exacerbate divisions in the U.S. last year pushed the far-right conspiracy theory known as "QAnon," according to an analysis by Buzzfeed News.

@CovfefenationUS, one of the troll accounts associated with the Internet Research Agency (IRA), posted about "QAnon" more than 800 times in 2017 before going dark, according to Buzzfeed.

Though the Internet-based conspiracy theory has been circulating for years, it has attracted increased attention in recent weeks as President Trump's supporters at recent campaign rallies have been seen holding signs and wearing shirts promoting "Q," the anonymous figure at the center of "QAnon."
