In a collection in person PayPal scheme, the scammer targets eBay auctions that allow the purchaser to personally collect the item from the seller, rather than having the item shipped, and where the seller accepts PayPal as a means of payment.
The fraudster uses a fake address with a post office box when making their bids, as PayPal will allow such an unconfirmed address. Such transactions are not covered by PayPal's seller protection policy. The fraudster buys the item, pays for it via PayPal, and then collects the item from the victim. The fraudster then challenges the sale, claiming a refund from PayPal and stating that they did not receive the item.
