Sounds like an ill conceived marketing strategy by Chase. They changed their plan after the loophole became apparent and their costs exceeded the benefit. While Chase's response mechanism is/was weak, they do have the right to cancel any program at any time.

I agree with Kokonutz on page two. Be happy with the miles that you received, and keep looking for new ways to earn miles. But...Anytime that the offer is too good to be true, it will be canceled when the Co. discovers it is a loser. -Too bad that they did not think the program through before initiation.
