> Also I think it is weird that when someone steals a bank card, they use it to buy adult games instead of buying an iPhone or MacBook and shipping it to the third world country.
iPhone or MacBook purchases are expensive enough to trigger fraud detection reliably. A $19.99 adult content purchase less likely to.
It's not just stolen credit cards, though. Adult content purchases have another problem where purchasers often deny having made the purchase when their significant other finds it on the credit card statement. Shaggy's "It wasn't me" defense.
