I know Microsoft can tell if you create more than one account from one computer or one ISP but what about those that aren't? I have some friends and middle age family members who use bing. If they sign up and don't want the rewards can they redeem say an XBOX Live Gold or MS Points code and then text/email the code to me? I mean if they're going to use it why can't I? Or is that against the service agreement. A lot of them are gift cards so maybe I'm being too hopeful.
