This article goes into my "arguments for Bitcoin" pile. More sellers need to recognize the risks involved in doing transactions through PayPal/any other credit card processor and protect themselves.
One day you will get robbed by one of these exchanges, and you will blame bitcoins (or the bad man) and swear to never work with Bitcoins again. But they will be just one link in a chain of exchanges that you've trusted each one, hundreds of times, to bring you music and movies for bitcash, and nobody will write an article about it.
I am a small volume user but I have never been scammed by anybody in Bitcoin, except for that Bitscalper fellow.
Don't you want to upgrade your currency, to the one where charge backs can not ever be issued against you, and its the whole world and science that keeps your money safe from hackers?
Then what?
Edit for accuracy: It's easier to verify the trustworthiness of a seller than that of a buyer.
If the item matches then return to the complainant (buyer) at the buyer's cost + add a service charge. Seller keeps all their money. Buyer's account marked for fraud watch.
If the item doesn't match then refund the buyer with a chargeback, return item to seller at the seller's cost + add a service charge. Seller loses their money. Seller's account marked for fraud watch; selling fees increased.
Items not paid to be returned can be sold on to help cover admin costs for items that buyer's or sellers do not want returning.
Note that in the OP ebay claim to have assessed that the items didn't match the description and so buyer protection is invalidated. But they haven't checked and so are defrauding the seller in respect to this claim.
