In several ways its actually worse than that, you can't release an app showing other user generated content, because a spammer could result in serving up advertisements, which aren't allowed. So no apps involving communication with other people. Even worse you can't make an app capable of displaying any 3rd party internet content because the 3rd party might embed an advertisement.
