Moderating the Fediverse: Content Moderation on Distributed Social Media

Current approaches to content moderation generally assume the continued dominance of “walled gardens”: social-media platforms that control who can use their services and how. Whether the discussion is about self-regulation, quasi-public regulation (e.g., Facebook’s Oversight Board), government regulation, tort law (including changes to Section 230), or antitrust enforcement, the assumption is that the future of social media will remain a matter of incrementally reforming a small group of giant, closed platforms. But, viewed from the perspective of the broader history of the internet, the dominance of closed platforms is an aberration. The internet initially grew around a set of open, decentralized applications, many of which remain central to its functioning today.
