Unfortunately, any money you have in that old account is probably gone for good. Other than the account recovery function, Steem Inc has no power to reverse transactions or freeze accounts.
This may sound strange but Steem is a decentralized crypto-currency. If a central authority could step and do these types of things, then it wouldn't be decentralized.
Exactly. Nothing is more important, than keeping this whole thing decentralized & iriversable. Even lost money... Sorry to say that.
