I've got a message from support that I cannot use the service anymore, and if I register a new profile they will automatically track it and block it. As I read from Uber's case it's forbidden by Apple to track app reinstallation. So how will they track me?
- advertisingIdentifier — I've disable it
- Geoposition — I hope they wont block all users in my area
- IP adress, social network profile — I've changed it
- App Store payments I've made — if I get it right, billing info is not visible to the developer. But is it possible for developer to know if a user installed an application paid for it before?
Are there any other ways to track users?
