The worst thing about it is that it looks exactly like a regular app listing, too. The only indication that it's an ad is a tiny "ad" icon - a pale blue square with slightly paler blue text. And that icon isn't even next to the (large and visible) app name, it's next to the (small and greyed out) tagline.
