Inspiration
Reddit moderators spend hours manually removing spam and toxic content. Medusa automates this so mods can focus on community building.
What it does
Medusa Auto-Mod monitors every post and comment in real-time. When spam, toxic words, or forbidden links are detected, Medusa automatically removes the content and posts a warning comment explaining the violation.
How we built it
Built on Reddit's Devvit platform using TypeScript. Used onCommentSubmit and onPostSubmit triggers to intercept content, pattern matching for detection, and reddit.remove() for enforcement.
Challenges we ran into
Devvit's architecture required careful loop-guard implementation to prevent Medusa from analyzing her own warning comments and creating infinite trigger loops.
Accomplishments that we're proud of
Real-time moderation working end-to-end — spam posted, spam removed, warning posted, all within seconds.
What we learned
Devvit's trigger system is powerful but requires precise permission scoping in devvit.json.
What's next for Medusa Auto-Mod
Claude API integration for semantic analysis beyond pattern matching.
