🚨 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.

Big news from #ICWSM2025! "The Susceptibility Paradox in Online Social Influence” by @luceriluc.bsky.social, @jinyiye.bsky.social, Julie Jiang & @emilioferrara.bsky.social was named a Top 5 Paper & won Best Paper Honorable Mention! 👏 Congrats to all!

It was a pleasure to present our research at @icwsm.bsky.social in Copenhagen with many friends and colleagues! Don't miss our work with @frapierri.bsky.social, Stefano Cresci, @luceriluc.bsky.social, @pettertornberg.com and @silviagiordano.bsky.social here: ojs.aaai.org/index.php/IC...

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...

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

ISI’s Luca Luceri partnered with Financial Times to uncover a coordinated online campaign influencing Canadian voters. Read about it here: bit.ly/3Sb598U @luceriluc.bsky.social @usc.edu @viterbischool.usc.edu

In collaboration with the Financial Times, our recent analysis uncovers a network of coordinated inauthentic actors engaged in amplifying misleading news content that promotes Poilievre while attacking Carney

Can we effectively detect covert Information Operations (IOs) that attempt to manipulate socio-political debates on social media? This is the focus of our work, "IOHunter: Graph Foundation Model to Uncover Online Information Operations", just presented at the #AAAI #AAAI2025

This work would not have been possible without the other amazing coauthors @luceriluc.bsky.social @frafabbri.bsky.social @emilioferrara.bsky.social Bonus Pic: myself beyond excited to stand next to my poster!

Shared some thoughts in this @time.com article on Meta’s decision to scale down moderation policies, noting it goes beyond discontinuing fact-checking time.com/7205332/meta...

Good day to boost this paper on the contrasting effects of lax content moderation (like on X and what is coming at Meta) and how they drive toxic content; by a team including @luceriluc.bsky.social and @emilioferrara.bsky.social arxiv.org/abs/2412.157...

What a Christmas gift🎁In our latest @realaaai.bsky.social paper, we integrate our coordination detection model with the power of LLMs & GNNs to enhance the generalizability of information operation (IO) detection in data-scarce scenarios and unseen IOs. Kudos [email protected] and our🌠team!

Our latest #icwsm paper is out! 👇 TLDR: We investigate susceptibility to influence by proposing a methodological framework to measure influence-driven content adoption mechanisms & We establish the Susceptibility Paradox: users’ friends are more susceptible to influence than the users themselves!

If you work on online platforms' trust & safety and are interested in detecting information operations and coordinated inauthentic behavior, this is the dataset you’ve been looking for!
