I recently sold a high-value, limited edition console on eBay. The winning bidder placed a high bid, then immediately began questioning the item’s authenticity - despite the listing being clear, detailed, and accurate. The buyer had the opportunity to ask questions prior to bidding and was even encouraged to do so in my item description, so there is no excuse for their conduct. They still haven’t paid and are currently ignoring my messages.After checking their feedback history, I discovered multiple other sellers had left similar comments warning of non-payment, refund abuse, aggressive messages, and suspicious behaviour. It was clearly a pattern.I reported the buyer to eBay, expressing concerns about their feedback history and their sudden questioning of the item’s authenticity after they had won the auction, but no action was taken. I was simply told to wait four days and relist if they hadn’t paid. That was it.Despite the buyer clearly abusing the platform, eBay offers no way for sellers to leave negative feedback, and repeat offenders like this continue to waste people’s time without consequence. eBay has made it nearly impossible for honest sellers to protect themselves, especially when selling high-value items.eBay is an unsafe platform for sellers. Repeat offenders face no real consequences, and customer support offers little more than scripted responses. If you value your time, money, or peace of mind - stay away!
