ICYMI: Moderation isn’t just rules; it’s how communities learn to stay fair.
@vinaykoshy.bsky.social presented Venire @CSCW. It learns Reddit mod decisions to flag borderline cases for group review.

Just arrived in Bergen for CSCW, where I'll present Venire! Venire is a Reddit moderation tool that uses an ML model trained on mod decision histories to identify controversial cases. It preempts inconsistent decision-making by flagging these cases for multi-mod review

Receiving positive feedback on Reddit leads to slightly more frequent & much higher-quality contributions (for some days). Sustained positive feedback can complement content moderation. (Cool to see obs studies at @chi.acm.org!)

In another #CHI2025 paper led led by Charlotte Lambert, in collaboration with @kous2v.bsky.social, we conducted a quasi-experimental study and found that Reddit users who received “high scores” and “gold” made more frequent and higher quality posts (i.e., higher scores and fewer removals).

In a #CHI2025 paper led by @fred-choi.com, we found that YouTube’s “creator hearts” served as an incentive mechanism to drive user engagement among bystanders. This was a collaboration with Charlotte Lambert, Vinay Koshy, and a team of SCUBA undergrads@Illinois!

Excited to be at #CHI2025 with SCUBA lab folks! @fred-choi.com and Charlotte Lambert will be presenting papers that highlight the effectiveness of positive reinforcement in shaping social norms and encouraging desirable user behavior.
Check out their talks at the 11:10AM session on Tuesday!
Q: Are fine-tuned SLMs better than LLMs at identifying online content that violate community norms?🤖⚖️
A: Yes!
