I"ve been playing a game on-line which requires a password, cookies and javascript in order to play. The problem we have had here is that some players have created multi-accounts to cheat. The admin claims he deletes any multi-accounts, and any accounts with same IP. He also assures us he uses the other info from the cookies to check out any users we feel are cheats in case they use a proxy to change IP. At his request I have from time to time checked him by creating other accounts using not only anonymous proxies, and logging in as a different user on my pc, but by changing my screen resolution etc.. to throw him off. He constantly is able to detect them and delete them.
The problem is there are several accounts that I know for sure are multi-accounts, yet they don't seem to get deleted.
My question is could these other accounts actually have a way of fooling his verification(and if so how can I prove it to him) or is he merely deleting only the accounts he chooses to, thereby favoring one side?
