Stoking racial tensions, funding activist campaigns and organizing fake street flash mobs were just a sampling of the “Kremlin’s troll factory” activities online in the months leading up to the 2016 U.S. presidential election, the RBC news outlet revealed in an investigation published Tuesday.

The St. Petersburg-based Internet Research Agency is believed to have launched a mass social media campaign using fake accounts to exacerbate racial and ideological divides in the U.S. before Donald Trump’s election last November.

“There was no task to support Trump” a troll-factory employee told RBC, adding that their orders were to “uncover and highlight existing problems and social issues in the United States.”

Some 50 employees currently operate out of the St. Petersburg-based “American department” of the Internet Research Agency, but at the height of their operations in 2016 the department had between 80 to 90 employees.

The campaign began in March 2015, when a night-shift vacancy for “internet operators” earning 40,000-50,000 rubles ($700-$870) monthly appeared on the job-search engine SuperJob, a former employee told RBC.

The description listed writing on “any given topic of a news, informational, or analytical nature” as the primary task. Applicants had to be fluent in English and possess creative writing abilities.

Currently, the “American department" receives 60-70 million rubles ($1 million) funding annually, RBC reported.
