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

X’s new location labels unmask users. Insiders say the idea was rejected for years.
A new feature meant to boost transparency on Elon Musk’s platform relies on data that researchers say can be inaccurate or easily spoofed.

🚨 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.
Comparison diagram showing traditional vs discourse network user representations. Left: isolated platform-specific clusters with no cross-platform connections. Right: unified network where users are connected across platforms through shared narrative engagement, revealing previously invisible cross-platform communities.

So satisfying to have some evidence that Elon Musk is wildly promoting himself on X. Researchers made 120 sock puppet accounts to see whose content is getting pushed on users. #FAccT2025 @jinyiye.bsky.social @luceriluc.bsky.social @emilioferrara.bsky.social doi.org/10.1145/3715...
