It's a terrible idea to just keep the card and act like nothing is wrong. With the group of Asian hackers who figured out how to crack the iTunes gift card codes, these scams are becoming more and more prevalent. I imagine it won't be too long until Apple figures out how to consolidate purchases made with iTunes cards which were bought and authenticated from real retail outlets, and codes which are generated by hackers. What happens when Apple figures out how to tell the difference between real iTunes codes and hacked codes is up in the air. They could give consumers the benefit of the doubt and just let everyone keep their codes, they could bill everyone who abused them, or a combination of the two. Emailing and being honest about it is the best course of action. jecebn doesn't know if the card he got is legit or not, he used it and it works, but that doesn't mean the suspicion is eliminated. Who knows, Apple could offer him a real gift card in exchange for information on catching people selling the hacked one. To just sit on it and wait to see if Apple does something is a terrible idea... Unless you don't mind the possibility of just randomly being billed $50 by Apple sometime in the distant future, have your iTunes account banned, or who knows what else when they get this all straightened out.
