If money is sent in one direction I don't think you are at risk. It is a legitimate payment. If your brother returned the same amount every month, now charged to his credit card, it would look funny to them. If they wouldn't allow mileage cards, would the usage drop dramatically? I bet it would. Would some people use it anyway as a way to send money too their kid at school, or pay the rent. Sure. Many people need to charge payments. I'm always a little suspicious when someone's first post is critical. Who are you really and why don't you post under your real handle. Clearly you have been here and posted here before.
