What does coordinated inauthentic behavior look like on TikTok?
We introduce a new framework for detecting coordination in video-first platforms, uncovering influence campaigns using synthetic voices, split-screen tactics, and cross-account duplication.

🚨 New preprint 🚨
Can AI agents coordinate influence campaigns without human guidance? And how does coordination arise among AI agents? In our latest research, we simulate LLM-powered AI agents acting like users on an online platform, some benign, some running an influence operation

New paper + interactive dashboard on the 2024 election information ecosystem.
Building on discourse networks work with @hanshanley.bsky.social @luceriluc.bsky.social @emilioferrara.bsky.social—this lets us visualize the online landscape as a unified system, rather than isolating each platform.
