Apollo13:
Problem is, this game has rules and TOS. So even if the app has bugs, it's still forbidden by the TOS to exploit them. It's like speed limits. In Switzerland, where I live, I go to jail if I speed with 250km/h on the highway. In germany, 50km away from my home, this is totally legal. I don't have to find any of these rules good, but I have to follow them or I will be punished.
I don't have a backup plan if GREE choses not to act. Sometimes one gotta raise his voice. History shows that these will always be flamed and hated. But still I feel it has to be done. I did this in the past and will do this in the future.
