Reddit Unveils AI Moderation; Old Reddit Is Restricted to Logged-In Users

Reddit is introducing AI-driven moderation built on large language models to help volunteer moderators enforce subreddit rules. After months of testing with more than 700 communities and members of its Mod Council Network, the Rules Hub is now available to newly created subreddits and will see a broader rollout later in 2026. Rules Hub lets moderator teams write rules in plain language while the underlying model judges whether posts or comments match those intents, and it can remove content it determines violates rules. The move aims to overcome limits of Automoderator’s brittle keyword matching and to work alongside existing Post and Comment Guidance and Safety Filters. Early acceptance studies suggest users often accept AI outputs, but whether volunteer teams will fully trust LLM judgment on nuanced community norms remains an open operational question.

Concurrently, the platform is tightening developer and data access: third‑party apps must migrate to a proprietary developer platform as public API access is gradually restricted, supported by a £780,000 migration program. This follows disruptive 2023 API changes and stems from concerns that the public API was not built for current scale, commercial scraping, or automated use by external AI firms. To curb unauthorized collection, legacy Old Reddit is now viewable only to logged‑in users, search engines and archival access have been limited, and legal action has been taken against some companies. Leadership stresses major features won’t be removed without credible replacements as it explores rebuilding the legacy desktop interface for a site with roughly 130 million daily visitors across 100,000 communities.
