Ebay is terrible.

I once sold a nice (and expensive) smartphone on ebay. The buyer complained that it did not arrive as described. The phone was fine, but whatever, I thought ebay would just refund the payment and have the buyer return the phone, right? Nope, ebay refunded the buyer and let them keep my phone! No recourse... nothing. Ebay let the buyer steal my phone!

That’s standard. This scam is nearly 2 decades old, except back then it was done via PayPal. I think you’ll find more by searching “PayPal chargeback scam”

This is exactly why they have an itchy finger on the ban button for new accounts.

There is no easy solution to the "I got a brick in the mail" problem, from either the buyers or the sellers side.
