Anyway to block a city? Or Address?

[bhtoys]

My website is getting hammered pretty hard from credit card testers. 

I had this problem before, so I set a default minimum of $10 per transaction - that helped... for about 8 months.

Now they're testing for items priced anywhere from $15 to $200

I've blocked a shitload of IP addresses - but they still get through. 

I've changed my keys daily - they still get through. 

So I'd like to block the postal code, or "city" name they use upon registration - both of which are fake.

I don't see a spot to do that - so, is this possible? Can it be done?

Hi,

Don't captcha modules block enough of these scammers?

Are they all from the same country?

Do you use CloudFlare?

You can maybe use an address checker that don't allow you to fill incorrect informations, otherwise you can of course block ranges of postal codes to register or use a basic ZIPCODE module that let you set a new transport area.. that will not be covered so they will never access to payment, but can register new account, so you'll have the trace.

Is there any payment that succed ?
