You are correct, unfortunately there have been times when an app banned by Apple can't be resubmitted because removing the content Apple dislikes would destroy the functionality or purpose of that app. This is mot a dig at Apple - iOS is their garden and they may do as they wish - but a general reminder that risk assessment is necessary when you build your business on top of anybody else's stack (be it Twitter, FB, Apple, Google or Amazon).
