a simple solution would be to be able to make reports without the need for evidence.
if a player is reported and his acc is "clean" nothing will happen to him,

the amount of player who breaks the rules of the game is absurdly large...
account sharing, account buying and selling, buy coins using VPN, all of this influences the imbalance in war for server.
