>> crooks always seem to find a way round it

If you get on an anti-fraud list you can be informed about known fraud IPs etc. and block these pre-sale.

Match IPs to countries, lookup addressess etc. In this way you can minimise fraud to a massive level. Sure, you may lose a couple of genuine sales, but the fraudulent ones cost a whole lot more.

Fraudsters can always find ways around any security measure, but most are lazy. Why persist with a secure and fraud-aware site when there's an insecure site a click away?

If would be wrong to ignore the economics of the situation. How much would it cost to investigate your 2 fraud attempts with very little chance of success compared to the many other types of crime?
