server ban just basically normal ban and you can still create new account and use same device, while device ban is basically any new account you use will be banned instantly and only way to get away from it is using new device. but i think there's more about banning system on this game. cuz on lib.initialize.lua and main.lua it loads alot of device information and also google play stuff and vise versa for other types like Apple and huawei. and also on profile file (game data) it had an encrypted PinCode and Key on line 1 and then followed with save_data in table. this is for cloud save checking and auth for online. i still doesnt understand how it works.
