Usually hacked paypal/ebay accounts. Once you Buy it now they get the funds and then spend it on digital goods or some other easy way to launder. So ebay/paypal eats the loss while you sit for a week with your thumb in your butt waiting for your funds to be returned.
This is how they do it.
He was stupid the better scammers list at 10 to 15 % lower then the lowest buy it now.
They list 3. Sell one to another account they control.
Give a good feedback for it. Say “ fast shipping good gear.”
Then sell two to normal buyers. Then buy a gift card and use it fast to buy tools at Home Depot or something else.
Oh, Okay. Actually, in my country, eBay used to hold the money that they receive from the buyer as an escrow service and once the buyer receives the item that they ordered, then after a day or two, they used to transfer the amount to the seller. So, any type of scams could be easily avoided as the money was still in possession of the eBay and they would refund it pretty quickly.
Anyway, I have always cautioned people online to not use PayPal to buy cryptos as the seller can easily register a claim and the buyer can get scammed.
