First lets think about why people spoof. First reason is that they are lazy because drops and dinos spawn too far away. So they start using fly gps apps to open drops and shoot dinos. So great fix to this spoofing problem would be to bring green drops and dinos closer. For example nearest green drop for me is 12km away and epic or legendary dinos never spawn near me. These long distances make players want to use cheats. But if you live in city there is no problem.
