44 The Senate Intelligence Committee bipartisan leadership jointly invited several researchers to pull together teams and examine the data sets. We were each unaware of the composition of other teams, to ensure that the work was done independently in light of the sensitive political nature of the election-related aspect of the material. The work was not a paid consulting engagement but rather a technical advisory relationship. The findings of the reports subsequently informed the Senate Intelligence Committee’s own four-part report investigating Russian interference into the 2016 election. The announcement of our work can be at “New Reports Shed Light on Internet Research Agency’s Social Media Tactics,” US Senate Select Committee on Intelligence, December 17, 2018, https://www.intelligence.senate.gov/press/new-reports-shed-light-internet-research-agency%E2%80%99s-social-media-tactics.

45 The cooking forum poster, “Alice Norton,” an “assistant cook” whose profile said she lived in New York, claimed her family had been poisoned by the turkey and her son was hospitalized. This message reached Twitter within a few hours, via nearly one hundred IRA-affiliated Twitter accounts that linked to the post and to a Wikipedia page that had just been created, called “2015 New York Poisoned Turkey Incident.” Wikipedia volunteers quickly took the page down for violating policies, but that same day a news story was posted on the domain ProudtobeBlack.com, a URL registered only a month prior, claiming that two hundred New Yorkers were hospitalized due to poisoned Walmart turkey supplied by Koch’s Farm and that their tip came through “our trusted sources in NYPD.” The claims were investigated by the Department of Health and Mental Hygiene, which had no records of any food poisoning episodes, and an executive at Koch Turkey Farm explained that they don’t even sell turkeys to Walmart.

48 Black women, frequent targets of online trolling, had begun to talk about accounts that attempted to manipulate the Black community, particularly around the time of Gamergate. They used the hashtag #YourSlipIsShowing to call attention to provocateurs that they suspected to be racist trolls from 4chan (later 8chan); subsequent research into IRA data suggested that some of the activity was additionally boosted, and joined, by Russian trolls who took advantage of real racial tension and shifting norms around online harassment. See, for example, comments by analyst Shireen Mitchell in this New York Times analysis of Russian troll messaging around the Women’s March: Ellen Berry, “How Russian Trolls
