Overview
The moderation system provides 7 layers of defense:
- Terms of Service — on-chain acceptance at registration
- Stake-to-report — 0.01 SUI required to file a report
- Auto-flagging — 3 independent reports trigger automatic flagging
- Council resolution — moderators review and resolve reports
- DAO proposals — community votes to flag, hide, or restore content
- Reputation-weighted voting — (Phase 2) vote weight from on-chain reputation
- Full transparency — all actions emitted as on-chain events
