The USA has a very high credit card processing approval and fraud rate but you need to understand why, most people are thinking 1999 style on fraud rate country banning -- and we profit by it
- Credit card fraudsters use VPNs and proxies -- they know their countries are on your shit list.
- Most of the stolen credit cards ( and stolen credit card data) is from the USA.
- Friendly Fraud on USA cards is very common, this has a lot to do with VISA (other card associations) and Banks accepting most customer claims. The customer says it was an unauthorized charge. In reality a member of the family used Mommy or Daddy's credit card on a porn site.
A lot of the USA credit card fraud is persons impersonating USA cardholders and then the banks issuing charge backs.
No credit card fraudster uses an IP from the countries on your 'lists' unless he is a total 'tard -- he knows you will block him
