This kind of thing is already against the App Store Review Guidelines:
> Push Notifications should not be used for promotions or direct marketing purposes unless customers have explicitly opted in to receive them via consent language displayed in your app’s UI, and you provide a method in your app for a user to opt out from receiving such messages. Abuse of these services may result in revocation of your privileges.
Apple has now introduced a way for developers to report other apps that break the guideiness. Rest assured I will be making reports every time an app sends me advertisement notifications that I did not opt in to.
