I dont have an address to sign tied to the account. The admins can clearly see my email was changed probably by some ip in eastern europe or something. Can't they just see that and reset it to the original email?
They can,they won't.
The only accepted way of proving account ownership is through signing messages from a staked address .About the IP tracing,resetting accounts being the least priority of the admins,they won't invest time to do all that hence signed messaged.I'm afraid you will ever get your account back if you fail to provide ownership.
