Years and years ago when we first launched a video chat room app, they denied it. They said it wasnt allowed to have a listing of rooms. So we simply had the app request a file from our server on app launch. If the file was present, we hid rooms. Once we got approved we just removed the file. We kept that up for a few months but it seemed like after the initial approval apple never bothered to check again so we just abandoned it after that.
Be careful, I once got this from Apple (they had misunderstood something about my app)
