Marco on iPhone Application Parental Ratings
The solution to this is simple. Add another ratings criteria to the form: “Unfiltered Internet Content”. Make it a simple true/false value instead of an intensity level. If set, the rating goes to “17+” and it displays only “Unfiltered Internet Content” below the app’s icon in the Store. Not that I have any hopes that Apple would actually _do_ that.
This makes sense— the ESRB does this with video games by adding a disclaimer about the unknown nature of online content. Hopefully Apple can switch to this but I doubt they see it as a problem.
