You have answered your question yourself...
I don't see why you're already calling him a scammer just because he's a newbie and he has negative trust.
What else do you need to spot a scammer when you see
PayPal +
Newbie +
Negative trust?
Maybe most people who have those transactions
are scammers. I looked at the OP's trust feedback and he's probably a scammer; but what I was saying is that guistone immediately started pointing fingers and began yelling "scam" without giving the OP a chance to offer escrow.
And the OP is selling bitcoins for PayPal, meaning there won't be any chargeback issues from the OP.
I'm just asking the OP if he will accept escrow.
