Go to the iTunes App Store, search for an app you want, and get your results flooded with spam-apps. Its a growing problem as unscrupulous developers keep finding new and annoying ways to try and game Apple's approval process and scam users.
Marco.org highlights some of the worst offenders, but more importantly offers legitimate developers a way to take action:
When an app is infringing on your copyright or trademark, the proper procedure is to send a clear notice to firstname.lastname@example.org citing your intellectual property and which apps are infringing it (provide their iTunes URLs to eliminate ambiguity). As part of this notice for trademark infringements, you can request that apps not be allowed to use your trademark to market themselves in search results (keyword spam).
Hopefully Apple will save developers the frustration and
