With 99.9% certainty, this user will disappear without a trace and any money sent to him goes poof.
Make it a hundred %. When someone says send the BTC first, its no just a warning sign but a hundred percent scam. A DT giving a red trust to these guys won't matter, he can jsut create another account and then do it again. What these scammers has to encounter so they will stop scamming users in the forum are regimen of scambusters. They'd be bombard with warnings whenever they post something as fishy as OP. They'd have to be trusted first before they can do these exchanges.
