# Fraud protection - Sales & 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 <mark style="color:orange;">**Don't record**</mark> to completely ignore those orders or <mark style="color:yellow;">**Flag order**</mark> 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.&#x20;

By clicking <mark style="color:blue;">**Blocklist**</mark>**,** you can review the blocked IP addresses. You can also unblock the IPs if you find them qualified or blocked by accident.
