We are not able to reveal how we detect cheating, since that would allow the people who develop these cheats to know how our security works and how to avoid detection. However, we have firm evidence that your account has been engaged in cheating. Please note that you are responsible for what happens on your account even if you choose to share your account information with another player. If another player cheats on your account, the account will still be suspended.
As we have determined that we will not be reopening this account, we must consider this matter closed and will no longer respond to support tickets about this account.
