Hello, I recently checked the stats of my game, i have best numbers of download from CHINA, but i never get a penny from that, most of people here have an iphone, but they never use apple store to manage their app, they just use kuaiyong, its allow you to get all your application for free, Kuaiyong use legal developer licence to distribute them, so player cant use IAP because its downloaded with an other dev account blocking all the developer to get income from IAP. is there someone that have experience how to avoid this? would it be possible to block their dev account ID to be used in your app? i can find it in xcode list of developper when i connect an ipad with kuaiyong on my computer. Im pretty sure the legal way in china will have no use, but if there is a way to block them to crack your app and block it income when they dont inject their own ads..
