I worked on a dating app that would almost always get rejected because the reviewer would find a profile that had partial nudity or someone in a sexy pose and would just reject the whole binary for that reason. Even for major bug fixes. Even for a feature we had added that would make it easier for users to report inappropriate photos on our app. They were holding back that feature because they found an inappropriate photo in the app. Updates would take on average 4 weeks to get approved. Very infuriating.
