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.
minor PP problems, trader was very nice. We figured it out.
UPDATE: I have received an unauthorized charge back on PayPal. I have contacted the buyer, this may be an error, but for the moment, exercise caution.
UPDATE 2: Buyer has not responded to emails or returned my contact here. I must assume fraud.
