dddWell I tried something called 'second space' it's either on your phone or you can download an app with the same name.
This 'second space' will allow you to create a copy of an app you want with a new everything it's like having a new phone.
But you said you were banned without linking with Facebook so the game might actually banned your whole device... I'm not sure if it's going to work for you but there is no harm in trying.
