| Step | FC2 Recommend Action | |------|----------------------| | 1 | Episode finishes | | 2 | Next rec: same anime, different uploader (higher bitrate) | | 3 | Sidebar recs: similar anime (different franchise) – likely copyright violation | | 4 | After 3 videos: pivots to unrelated adult content (maximizes session time) | | 5 | 24h later: homepage “Because you watched…” includes the original leak again |

| Feature | Observed Mechanism | |--------|-------------------| | | New videos recommended via uploader’s historical tags & geo-IP (Japanese users see JP-first) | | Collaborative filtering | “Users who watched X also watched Y” – but with high churn (abandons history quickly) | | Session-based | Strong recency bias – last 3 clicks dominate next 5 recommendations | | Click-through weighting | CTR > completion rate. A 10% CTR with 30% completion beats 5% CTR with 80% completion | | Dark patterns | “Recommended for you” includes unrelated shock content to test user tolerance | fc2 recommend
