If there's one guideline that's violated the most on iOS it's the block on direct marketing for push notifications. If you go by the developer agreement you shouldn't be sending push messages telling people a new update for your app is out, let alone direct marketing. But everyone ignores it, probably because Apple don't really enforce it. Some of the examples shown here aren't necessarily push ads though: you could imagine a restaurant app where you opted in to receive deals pushed in your area. But yes, I don't think users appreciate these kind of messages unannounced. Until Apple start enforcing it though, it's just going to keep getting worse...
