Case Studies

On Aug. 16, 2019, an anonymous user posted to 4chan’s Politically Incorrect board calling upon fellow 4chan users to impersonate Jewish people online by creating inauthentic social media accounts. In the days that followed, campaign participants created dozens of fake Twitter accounts, many of them posing as rabbis and using stereotypically Jewish names. Twitter quickly removed the accounts, although not before their owners could post inflammatory, often-antisemitic, and anti-Israel sentiments.

During the Oregon wildfires of September 2020, rumors spread locally and nationally that left wing activists had intentionally set the fires based on a series of misidentifications and inference by public officials. The rumor was amplified from partisan influencers on the far right, fake antifa Twitter accounts, anonymous trolling communities on 4chan, the QAnon conspiracy network, and late stage attention from President Trump.
