Fraud Control

There is no option to block the whole domain from which the fraudulent transactions / abandoned fake baskets come from. In my case it's @example.com . Multiple different emails from this domain. I cannot possibly block each and every fake email address, I would like to block the whole 'example' domain. Also, there is no option to block specific names/customers.

My store is being used to test stolen credit cards. It only blocks high risk transactions. I cannot block medium risk transactions. I've had multiple chargebacks and considering shutting down my store. No help from Shopify.

The app is useful if you take the time to understand and configure the rules correctly. Managing the messaging shown to customers when a checkout is blocked is important, as the default language is too soft for effective deterrence.

One major drawback is the lack of visibility into who is actually being blocked at checkout. All blocked users remain anonymous, so you only see aggregate counts rather than actionable detail. Greater transparency here would significantly improve the product.

Lastly, you can edit what the blocked customer sees by searching the language for "Decision rule block"
