We have released the first version of MADOC!
Huuge dataset with ~9M posts, 236M comments, and 23M users from Reddit, Voat, Bluesky, and Koo.
MADOC mixes benign and controversial/banned communities, ideal for the study of hate speech, user migrations, and community moderation.

Can LLM agents reproduce online community dynamics?
We simulated Voat's v/technology community with YSocial and uncensored LLM.
Simulation reproduces: activity patterns, network topology, toxicity distributions + decent topic coverage ✅

MADOC paper accepted at #ICWSM 25!
Looking forward to share more insights from the dataset in Copenhagen.
The dataset will be updated soon: bug fixes and additional sentiment scores.
