Decentralized moderation is difficult. For privacy and federation reasons, no server and no server admin has access to all the data and all authorizations. Bots could have access to authorizations but how can you deploy then, trust them and how can you make sure that they also have access to all data? In this presentation, we'll show some of the ongoing work on Mjölnir for All, an exciting project that aims to transform moderation on the Matrix network, without end-user configuration.
