I recommend using "No Fraud Fraud Protection", has everything I need and customer service is friendly. You can ***only*** get the Blacklist option via request. And even after request there is no convenient button to use so you always have to use the link they give you. Pretty basic need for a "fraud app", but no - they don't have it

Lightning fast customer support and super helpful with customer support ideas for contacting customers

FraudBlock Fraud Prevention will cancel the order and refund the customer but with 3rd party fulfillment networks that fulfill immediately after the order is placed, doesn't detect. I lost $3,000+ depending on this app to do this job when I should have done my own due diligence.

This is a really great and simple app. It has the ability to cancel and refund orders automatically, which can save you a significant amount of time and money. You can also whitelist your customers once you confirm that they are safe. Would recommend this app 100%.

I don't know what i would have done without this app. FraudBlock has saved me thousands dollars by instantly canceling all high risk orders. I have used this app for 2 months and that was the best decision i made after suffering damages from such fraudulent orders. The best part is the app does all of those fantastic things for free.
