I believe that all merchants #P2P #P2PScamWarning know they should not accept payments from third parties. Additional verifications, such as requests for documentation, often reveal that for the most part they are maneuvers that are part of scam crimes where the money ends up in other countries in less than criminal hands, and the seller ends up being a link. Personally, I always report suspicious activity. Everyone knows what they are doing and the consequences of their actions, but especially for the newer ones, it is preferable to lose a couple of orders that perhaps can be recovered seconds later in a legitimate transaction.
