I was wonderring, what is the estimated amount of Fraud on Domain systems (like NameCheap), and shared/reseller hosting services. And where do we get more fraud, PayPal or Credit card. Now, PayPal fraud can be repeled only accepting eChecks, credit card is not.

I was wodering, if for example I have an ENOM $6.95 account with DRAMS, someone register 6 domains with me pays via Credit Card, domain is registered. 60-90 Days later CHARGEBACK the payment made. Do I still have to pay ENOM or I just give Enom the Domain?

On Authorize.net you can check if the address and Zip code matches, what to do if it doesn't match?, and what countries have the most fraud %.
