no one will do that u have no vouches and most likely u will take the pin and run no offence i am not saying u are a scammer but u should use omm at all times no exceptions.
I would not trade with this person if i were you. I asked him to prove in game that he owns the account and he logged off straight away. He would also not go first, us a OMM or basically anything. Lookout people he just wants to scam
