"Through this research we gained insight into tactics employed by state-backed social media disinformation. With that goal, we explored user interactions with inauthentic Twitter accounts. We used multiple procedures to measure the ways in which users talked with and about the accounts employed by the Russian-affiliated Internet Research Agency in the month before the 2016 U.S. Election. We found that users were overwhelming supportive of the IRA accounts, a fact that calls into question the standard representation of these accounts as “trolls.” Users were particularly supportive of the accounts that pretended to be part of a particular ideological group (on both the left and right), supporting arguments that a strategy of building connections with like-minded people was central to the IRA campaign. This strategy seems to work—on days that the Russian accounts received more support they also received more engagement." (Lay summary)
