salient even as their tactics have remained remarkably constant. Today an ISIS supporter might adopt a pseudonym to harass a critical journalist on Twitter, or a right-wing agitator in the United States might smear demonstrations against police brutality by posing as a thieving, violent protester. Any major conflict is accompanied by a raging online battle between trolls on both sides.

Management was obsessed with statistics — page views, number of posts, a blog’s place on LiveJournal’s traffic charts — and team leaders compelled hard work through a system of bonuses and fines. “It was a very strong corporate feeling,” Savchuk says. Her schedule gave her two 12-hour days in a row, followed by two days off. Over those two shifts she had to meet a quota of five political posts, 10 nonpolitical posts and 150 to 200 comments on other workers’ posts. The grueling schedule wore her down. She began to feel queasy, she said, posting vitriol about opposition leaders of whom she had no actual opinion, or writing nasty words about Ukrainians when some of her closest acquaintances, including her own ex-husband, were Ukrainian."
