I understand for the first 3000 levels are not so difficult such as after 5000 level. At this specific case the cheating person passes in one day 300 levels. It is obvious and very clear that is cheating. I know that is not paying.
As far as I know this person dont have any experiance is very new to the game. Its obvious that is cheating. I know it. Everyone can do what ever they want? no rules or penalty?
