# Fraud protection - Sales & commission ## Sales and commission ### **1. Detect duplicate referrals from an IP address** This function also helps prevent suspicious sales from an IP address. You can set a period for the system to automatically detect if there are repeated sales from an IP address. You can choose **Don't record** to completely ignore those orders or **Flag order** to still record while flagging them.

{% hint style="warning" %} ***Note***: The preventive action will be taken from the following order that affiliates refer within the set period. The **maximum value** for Period is 31536000 seconds (365 days). {% endhint %} If you choose Flag order as an option, the system will automatically add a yellow warning next to the referral ID to inform you that this referral has been detected as fraudulent.

### **2. Block sales from IP addresses** If you know the IP address that brings suspected sales to your store, you can permanently block sales from this IP address for good. Please make sure to press **Save** to block it completely.

By clicking **Blocklist****,** you can review the blocked IP addresses. You can also unblock the IPs if you find them qualified or blocked by accident.
