Flagspill is an anonymous social platform where users share short takes on relationship and dating situations, then vote them red flag, green flag, or contested "yellow flag." It's Reddit meets a polling app, focused on the moments people overthink and want a second opinion on.
Features:
Anonymous post and comment system with optimistic vote updates
Multi-feed browsing (Hot, New, Top Today, Top Week, All Time)
Yellow flag detection for contested posts where the community is split
Responsive masonry grid layout that adapts cleanly across devices
Real-time engagement metrics on every post
Where it gets interesting is the moderation. Flagspill runs a multi-stage moderation pipeline using regex hard rules, heuristic spam and gibberish detection, and GPT-4o-based content review with rate limiting. Every submission goes through this pipeline before hitting the database, keeping the platform safe and useful at scale.
Tech stack: React, TypeScript, Tailwind, Supabase for database and auth, OpenAI GPT-4o for moderation, deployed on Vercel.
Built and shipped solo. Live at flagspill.com (http://flagspill.com).
