I'm on a Mac so I can't look, but... That kind of fraud is pretty rampant on the Windows Store, unfortunately. Its a game of whack-a-mole, and Microsoft is kind-of bad about removing them (because that hurts the all-important we have x-thousands apps in our store stat). They've been doing better lately. Make sure to report it, if you can.
By the way, this is one of the biggest reasons Apple charges $100 per year to get into their store, so at least, they have to make $100 before they get caught to make it worthwhile, and there is a little barrier-to-entry (you have to have a unique credit card and other stuff each time you do it).
It doesn't stop all the fraud, but a little of it anyway.
