PayPal is one of the riskiest payment methods and a favorite of scammers. Ask for ID with selfies and signatures and check for photoshop. http://fotoforensics.com/ It is best to call PayPal and tell them you are selling bitcoin as they allow it.
Seems to want to use a $20 ($18.92, really, because they made me eat the fees) PayPal transaction to set people up to do larger trades where they release before Dolly2R pays anything, leaving the seller with no protection.
Was leaving Neutral, but they gave me a negative in retaliation and opened a dispute with PayPal, even though they got my BTC.
