Artyom Baranov, who worked at one of Project Lakhta’s affiliates from 2018 to 2020, concluded that his co-workers were, for the most part, people who needed the money, indifferent to the themes they were asked to write on.

“If they were assigned to write text about refrigerators, they would write about refrigerators, or, say, nails, they would write about nails,” said Mr. Baranov, one of a handful of former trolls who have spoken on the record about their activities. But instead of refrigerators and nails, it was “Putin, Putin, then Putin, and then about Navalny,” referring to Aleksei Navalny, the jailed opposition leader.

The job was not to put forward arguments, but to prompt a visceral, emotional reaction, ideally one of “indignation,” said Mr. Baranov, a psychoanalyst by training, who was assigned to write posts on Russian politics. “The task is to make a kind of explosion, to cause controversy,” he said.

When a post succeeded at enraging a reader, he said, a co-worker would sometimes remark, with satisfaction, Liberala razorvala. A liberal was torn apart. “It wasn’t on the level of discussing facts or giving new arguments,” he said. “It’s always a way of digging into dirty laundry.”

Feminism was an obvious target, because it was viewed as a “Western agenda,” and hostile to the traditional values that Russia represented, said Mr. Baranov, who spoke about his work in hopes of warning the public to be more skeptical of material online. Already, for months, Russian accounts purporting to belong to Black women had been drilling down on racial rifts within American feminism:

“White feminism seems to be the most stupid 2k16 trend”

“Watch Muhammad Ali shut down a white feminist criticizing his arrogance”

“Aint got time for your white feminist bullshit”

“Why black feminists don’t owe Hillary Clinton their support”
