Yes if you're using standard paypal transfers, but no P2P trader would accept that, they will only accept the friends or family transfer which cannot be reversed

I've had many P2P scammers try to abuse this system, where they will claim I can refund the paypal myself and I should cancel the Bitcoin escrow, but only they can refund a Friends and Family Transfer, lol so I just let it ride let the moderator release the coins

I've been flagged on a few scammer chats with my various nyms so scammers won't often do business with me, and let me scalp those low premium or below market sales
