Adrian Chen, the New York Times reporter, conducted his own investigation into the Putin’s troll factory in St.Petersburg more than a year ago. He failed then to find out some proofs of existence of the Internet Research Agency LLC. But some events on the Internet like stove-pipings on the news resources and fake accounts of commentators were the undocumented proof that troll factory really exists and works. In the beginning of 2015 there was a conflict between the Agency and their former employee, Lyudmila Savchuk. All the known info about pro-Kremlin troll farm on the date of June 2 Adrian Chen collected in the article “The Agency”.
