It is actually a trading exchange website account Bitfinex. I have asked several escrow experts for there service but they said the price is very low. So I felt helpless and lonely in the huge crypto world. Imagine that.
Don't buy that account.You will be scammed/banned over time.
P.S. Do you mean you are willing to help for free? That super nice of you. But about the warning I think its ok because the user is unverified on the exchange so once i get the account I will get it verified and its most likely safe to use it wouldn't it?
The user will wait for you to get that account verified and then claim it back from the website by providing them required evidences.The escrow will be helpless in this case as original account owner is always free to raise a concern with the website and claim his account back after the trade.
