We examine how written moderation rules evolve as communities grow: 🔹 Do larger communities introduce rules covering different topics? 🔹 Does the way rules are written change with community size? 🔹Do differences tell us about how decentralized communities approach moderation at scale?

How do federated platforms manage content moderation? What does moderation look like when there are no monetary incentives and communities are run by volunteers? And how do these communities adapt as they grow? These are some of the questions we tackle in our paper: dl.acm.org/doi/pdf/10.1...

ACL 2026 was fun! We presented our benchmark, which reveals that frontier models struggle to moderate pluralistic communities on Reddit. A fun bonus: creating all the colorful plots for the paper! 🎨 Our paper, code, and benchmark are all available here: github.com/osome-iu/Plu...

👍 Engagement patterns differ across languages, revealing distinct communication ecosystems. More qualitative research is needed to understand how health info spreads in Spanish-speaking communities and how local institutions shape public health messages online. #BreastCancer #HealthComms

🤷‍♂️ Spanish-language posts mainly come from local governments, media, and municipalities. Many promote at-home self-exams—no longer recommended in the U.S. Most engagement comes from health sites, politicians, and local reps, showing distinct voices shaping Spanish-language breast cancer discourse.

Rasika Muralidharan @rasikamurali.bsky.social · 20/10/2025

🧩 English-language posts are mostly from major non-profits like Susan G. Komen and the National Breast Cancer Alliance. These groups lead awareness efforts, driving engagement through strong branding and messages focused on screening, survivorship, and fundraising in the U.S. #BreastCancer

🧠 Findings: 💭English and Spanish language content centered on similar topics—mammography, breast cancer awareness events, Pink Ribbon Month, and personal narratives.

⚙️ We employed topic modeling to identify clusters of topics discussed in Facebook posts related to breast cancer. Metadata analysis was then used to determine the primary sources of content and the types of posts that received the most engagement.

🔮 As LLMs evolve from individual tools to collaborative agents, understanding their team dynamics becomes essential. Applying team science offers a powerful lens for designing AI systems that collaborate effectively, leverage diversity, and adapt like human teams do.

Rasika Muralidharan @rasikamurali.bsky.social · 13/10/2025

🧠 Key findings 🧩 Agents tend to overestimate team performance before the task; post-task reflections surface misalignment and integration difficulties. 🧑‍⚖️ Evaluations via GPT-4o (“LLM-as-a-judge”) agree that flat teams score better in comprehension, coherence, reasoning, and confidence.

Rasika Muralidharan @rasikamurali.bsky.social · 13/10/2025

🧠 Key findings ⚖️ Flat (decentralized) teams often outperform hierarchical ones on reasoning tasks. ⚔️ Diversity is a double-edged sword: it can enrich reasoning in some settings, but also introduce coordination friction especially under hierarchical structure.

Rasika Muralidharan @rasikamurali.bsky.social · 13/10/2025

We designed flat and hierarchical teams of LLM agents, assigning them personas (e.g. demographics) to inject controlled diversity. These teams were tested on reasoning and social reasoning tasks. We combined quantitative performance evaluation + qualitative analysis to analyze interaction dynamics

Rasika Muralidharan @rasikamurali.bsky.social · 13/10/2025

New preprint! 🚀 We ask: What happens when you bring human team science into the design of multi-agent LLM systems? In particular, how do team structure, diversity, and interaction dynamics influence how AI agents collaborate? 📄Full Paper: arxiv.org/pdf/2510.07488 👩‍💻Code: github.com/Rasikamurali...

So about ten years ago I found a small network of bots on Reddit dedicated to spreading hate. The thing about it is that these weren't even responding to political topics - they were just responding to random keywords with insults and hate. The same bots are now here. You should understand why. 🧵
