I still don't see why everyone seems to think that crappy products and sellers are necessarily eBay's responsibility. I've always thought they made it pretty clear that they are just the auction vehicle and that the majority of the business is between buyer and seller. If I buy a shirt from Wal-Mart and it disintegrates in the wash, it's the manufacturer's fault, not Wal-Mart's. They didn't make the shirt. Of course, I already know that Wal-Mart sells cheap junk. But then I don't bid or BIN without looking at feedback and I don't buy secondhand items without contacting the seller first to a) double check on the item's condition and b) see if the seller is present and paying attention.

A lot of people just do negative feedback but don't file complaints. There are way too many sellers for eBay to monitor feedback--that's why it's available for buyers to check on their own. File a complaint or it's not going to count.
