The problem is, the hackers wouldn't use these gift cards to download music, but to sell them to unsuspecting victims.
I get that, but let's say they sell them on Raise.com, they lose a ton of money (probably would get less than the cash demand) cause no one pays full price for gift cards and then there are fees, Apple kills the cards, people that bought them on raise are pissed cause they can't use them, file a case, find that they were fraudulent cards, reverse the purchase of the gift cards, hackers are left with nothing.
F'ng amateurs, dude.
Serisouly, they sound like 8 year olds, dude.
