eBay never protect sellers either. I already have a few times problems with kind of scam buyers with all of evidence but never got any helps from eBay. They just stay in buyer side for all of the time. The last time I sold the laptop for bidding, the buyer received the item and changed the LCD, we have all of pictures and video shows that we opened the box, took out the laptop, checked and took pictures to send them. First they said they saw the different in the pictures and let me won the case, but after 24 hours they said the buyer won the case without any explanation to me. The pictures show clearly that 2 LCDs are different. They took the money out of mine and refund to buyers.
Either eBay has seller protection but seller NEVER GOT PROTECT when seller has to face with kind of untrusted buyer.
