I've noticed that there are so many reviews posted for apps where it's obvious that the poster never purchased, downloaded, or used the app that they are supposed to be reviewing. this really creates so much noise and pisses me off. A lot of reviews and ratings are suspect and idiotic especially when coming from non-users. In addition, it's open to abuse from developers and fanboys of a particular app who are more interested in promoting some other application then reviewing the application in which they posted their supposed "review". Especially when the system allows you to make up reviewer names on the fly so that it can seem as several people are posting similiar bogus comments. Apple seriously needs to limit feedback to only those that have paid for and downloaded an application. And they need to force us all to register under a specific nickname so that when posting a review the poster's nickname can be displayed and not made up on the fly.
