# 11.3 Fraud Detection & Account Control

* **Fraud Detection Examples**
  * Excessive BINDs at the same store (limit: once per 4 hours).
  * Mismatch between check-in location and payment location.
  * Abnormal earnings flagged via past 30-day scans.
* **Penalties**
  * Temporary suspension of withdrawals / NFT transfers.
  * After investigation: possible asset confiscation, BAN, or rank demotion.
* **User Notifications**
  * Fraud flags trigger in-app and email alerts.
  * Restored immediately once behavior is validated as normal.

👉 The system is designed so that **honest players are never penalized**.
