New Internet Scam

So I heard about a new scam where legitimate vendors (such as fandango) partner with companies that put a link at the bottom of the legitimate company's checkout page that says Click Here to Collect . If you click on that button, the Bad People grab your credit card info out of the legitimate company's cookie. If do not explicitly opt-out from the page they send you (e.g. you decide it's crap and close the window), congratulations, you're now signed up for a monthly "service" that you'll be billed a small amount of money every month until you notice the innocuously named charge and get it cancelled. Nice, eh? Google "MLI scam" and see what I mean.
