I think the relevant statistic to track would be ($ in attempted fraudulent transactions) / ($ in attempted legitimate transactions). I think that would answer the question of why a country like Cameroon shows up on the black list while Australia does not.
I agree. I would be interested to see some sort of analysis of quantity of fraud per thousand transactions on a country by country basis. I think it would be much more useful than the percentage of global fraud that each country is responsible for.
