·No, not with ebay. BUT, you could be assessed higher fees if you receive poor feedback. That's the bigger reason you don't want poor feedback. Outside of the perception of low integrity to potential buyers (your seller rating is posted on each of your auctions), anything less than steller can increase your sales costs if ebay increases your fees. Managing your rating is a big deal. Everything but perfect transactions count against you. That's why some buyers try to extort sellers with threats of poor feedback. They know it matters, alot.
Anyways, that buyer could well be a scammer, who hacked someone's old account. eBay like a mine field nowadays.))))
