From the experience I'm having, here are the requirements not to be banned: Do not use God mode and just use the currency freeze to get the resources and evolve the heroes a little every day. Do not evolve the heroes to the maximum level all at once in 1, 2, 3 days or a week. They know that it is practically impossible to evolve so quickly and the system automatically detects, banning the player. I will try to evolve 1 hero per month to the maximum level. So the system doesn't see it as a cheat. We need 5 heroes as a team, so choose which heroes you want to use in battles to evolve them a little each day until you reach the maximum level.
