A building in St. Petersburg, Russia is filled with roughly 400 well-paid trolls spamming the internet with pro-Kremlin and anti-Obama propaganda, according to an exposé in The New York Times Magazine by Adrian Chen. The clandestine operation, most commonly known as the Internet Research Agency, has been behind huge media hoaxes, including one that lead people to believe ISIS terrorists caused a chemical plant in Centerville, Louisiana to explode on September 11, 2013.

Employees maintain several fake identities online, fleshed out by numerous social media accounts. Working 12 hour days, the trolls use these various accounts to make political posts and comment on each other's feeds, most of whom don't necessarily agree with the opinions they express through their avatars.
