Do you know if I could get banned for sharing my account?  For example, logging in to game center/facebook/google+ and uploading RR3 account to friend's device, then have them log back on and saving it to their account?  Do you think I will get banned?  I've done that once, but that was to move my dad's account to mine. (I originally played using my dad's account and i decided i did not want to rely on his account, so I made my own account to save it in.)  Will it be better to save it through game center or google+ (those are the only 2 accounts I have).

Thanks for your help! :)
