Reddit Launches AI Moderation and Restricts Legacy Interface Access

Reddit Inc. is rolling out Rules Hub, an AI-powered moderation system built on large language models designed to interpret the intent of community rules through plain prose rather than keyword matching. After testing in over 700 communities, the tool is now available for all newly created subreddits, with a full site-wide rollout expected later in 2026. The system is intended to eventually replace the legacy Automoderator, though the company has pledged to maintain the old system until replacement workflows are proven capable.

These updates are accompanied by stricter data protection measures. Reddit has restricted the classic "Old Reddit" interface to logged-in users to prevent unauthorized automated data collection and commercial scraping by AI companies. This follows legal actions against firms such as Anthropic and Perplexity. Additionally, the company is restricting open public API access and requiring third-party applications to migrate to its proprietary Reddit Developer Platform, supporting the shift with a $1,000,000 migration program.

Volunteer moderators have criticized the transition, arguing that Rules Hub lacks the functionality of Automod and cannot effectively manage complex community rules. In response, Reddit officials clarified that the AI toolkit is intended to support both intent-based and deterministic workflows rather than forcing all moderation into an LLM. CEO Steve Huffman stated that the company is considering several options for the legacy interface, including limiting access or rebuilding it on a modern tech stack.
