Cracking the Code for Deactivated Accounts

Well I have a couple of accounts which are deactivated, and I do not know the email as well, as well as that I faked all the info, as this was an account which I made for an event which happened in '08 where you would get a free 5K maple points if you got a new account to 20. So I only know the password to the account, and the password to the email but I actually dont know what the email is. I've heard that if you log on paybycash on a verified account and then copy and pasted to the deaactivated account you can actually find the email but I dont get what they are trying to say. Is there anyway of finding the emai(s)l to my account?
