He is obviously a scammer by the looks of it.
The fact that he refused escrow should have been alarming enough, in my opinion, because if he was legit then he would have accepted any forum escrow that you would suggest. Telling you to send half of the amount first is a common tactic that scammers use, because it generates a false sense of security for the buyer. You are not protected by escrow if you send first any amount, period, and could get scammed.
DT members will tag him as soon as possible. Please update the OP with the screenshots links in the "proof" section, instead of posting it again in a reply.
BTW, what kind of business are you carrying on that requires 5 new PP accounts every single day? It sounds fishy for sure. It's against the PP terms and conditions as well, so I suggest stop doing it. Even getting a friend's paypal (if he is willing to take on the risk, that is) would probably work better tbh. A lot of these paypal accounts are actually fraudulent, hacked, or a result of identity theft.
