Primary account compromised

[arhjayy]

I stopped using MPGH around June(I think) as I stopped selling Minecraft accounts, I recently have decided to start selling again, but upon trying to login I found that my password was not working. I tried to reset the account password, but the email which was attatched to the account is no longer attatched. Upon further investigation I found that someone has been actively using my account,(pretending to be me?) probably responsible for changing the email and password of the account.

The Skype listed on the account is the.jokerhf which is definitely not me. If you have logs that far back you could see that the IP(and country IP) of the user has changed.

I will try to provide any proof I am able to to show that I am the actual owner of the account, I am just not sure how I can show I am the actual owner. This is quite crazy that he is just using my own account as if it were his own.

Main account: member.php?u=3057087
Main selling thread when I was using the account: showthread.php?t=918285
You can see he no longer does anything related to Minecraft and doesn't respond to any enquires about it.
