>>" You need to show them that most fraud actually comes from the US, even much of the 'Nigerian' stuff.
Then perhaps they will block themselves from us instead.">
You don't understand the problem.
The US may have a higher *NUMBER* of cases of fraud, simply because there are more people. But the overall percentage sales that are fraudulent is small.
Nigeria and Macedonia may only account for a tiny percentage of Internet sales, but out of those few sales, a very large percentage are fraudulent -- a much higher percentage than the US or western Europe.
If you are running a business, you quickly learn who to avoid.
Then there's the whole problem dealing with things on an international level. It's much easier to deal with fraud that comes from within your own country than when it comes from a "foreign" country, especially one where law enforcement is more lax -- and that's exactly what the fraudsters are counting on.
