Abstract

Recent evidence has emerged linking coordinated campaigns by state-sponsored actors to manipulate public opinion on the Web. Campaigns revolving around major political events are enacted via mission-focused “trolls.” While trolls are involved in spreading disinformation on social media, there is little understanding of how they operate, what type of content they disseminate, how their strategies evolve over time, how their behavior compares to benign users, and how they influence the Web’s information ecosystem. 


In this talk, we will present our analysis on Russian and Iranian trolls on Twitter and Reddit. We will shed light into these questions by undertaking a large-scale quantitative analysis of the text and images posted by state-sponsored trolls on the Web.
