Sorry noagenda. Being your attorney (according to valarius lol) I'm going to have to shut you down.
Amazon.com will have the right to close customer accounts and bill alternative forms of payment if a fraudulently obtained Gift Card is redeemed and/or used to make purchases on amazon.com or endless.com.
That's from their TOS for gift cards. If you spend the card, and later it is determined to be fraudulent, they will bill the user of the card for the amount of the gift card. Yikes. Not very friendly...
The TOS is unenforceable. A company cannot shift liability arbitrarily to an uninvolved individual who may not be aware that the card was obtained fraudulently. This is another unfortunate example of a company, like Paypal, that responds to fraud against itself by committing fraud against its own customers.
The TOS language was not strong enough to be enforceable. If Amazon really wanted to get away with this, they would have to admit prominently that the Gift Card actually has zero value. A reasonable person expects a gift card to function like company paper.
