An AI "army" flooded TikTok during the Iran War. Not one of the soldiers was real. At dotNex.ai, we traced the operation: 110 fake accounts, 3.9M views, one AI pipeline — engineered to shape how Americans feel about a war. Read the full report at reports.dotnex.ai

Luca Luceri@luceriluc.bsky.social · last yr.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. 📄https://arxiv.org/abs/2505.10867
🚨 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.
