Valve has announced a change to the Steam Gift service the company hopes will thwart one regularly occurring method of scamming.

As it has stood for a while, a scammer on a forum or in chat would offer a game for, say, an item they wanted. They'd trade players the game as a gift, receive the item they want and then cancel payment on the gift thus removing it from the recipient's inventory.

Pretty lame, right?

Valve's new rules make it so that any game purchased as a gift can't be traded for 30 days. That would give enough time for payment to clear and eliminate the chance for scammers to backout of a purchase they never intended to officially make.

Valve says that you can still gift the gift at any time, just like normal. This only affects trades. Valve offered this alongside the announcement:

We've made this change to make trading gifts a better experience for those receiving the gifts. We're hoping this lowers the number of people who trade for a game only to have the game revoked later due to issues with the purchaser's payment method.

Do you see any glaring problems with this new counter-scamming idea?
