# Manage lists (/platforms/checkout/advanced/customize/fraud-protection/fraud-protection-advanced/lists)



The **Lists** tab shows the attributes for which your merchants can create lists, the number of items on each attribute list, and whether an active filter is associated with each list.

Merchants can use **Blocklists** to prevent known bad actors and **Allowlists** to ensure their trusted customers can check out smoothly. **Reviewlists** automatically queue transactions with specific attributes for manual review, allowing the merchant's team to decide whether to approve or reject them.

> **Info:** Adding an item to the list does not ensure that the filter for the list will work for the newly added item. You need to create a filter again and specify the necessary conditions. Select **Create Filter** to set up the filter as shown below.
