He scam you? can you show some screenshot as a proof?
Given you haven't read the flag entry, allow me to quote it to you:
Timelord2067 alleges: Due largely to the factors mentioned in this topic, I believe that anyone dealing with red023 is at a high risk of losing money, and guests would be well-advised to avoid doing so. This determination is based on concrete red flags which any knowledgeable & reasonable forum user should agree with, and it is not based on the user's opinions.
The red-flags being the OP (red023) refuses to accept that PayPal is a reversible mechanism of payment - a well known method for scammers to scam.
