Sellers do have a right to give feedback. But I got burned with a negative feedback from a seller when I gave him a negative that was justified.
So there was that element of retaliation that kept buyers from leaving feedback
Ebay was much more enjoyable years ago. Meg Whitman made it into a money grubbing place that sucks for sellers. The money grubbers being the ebay corporate structure. Ebay is in need of competition
I think the sense of community has been lost.
I too got a retaliatory negative from a seller who successfully ripped me off. It added insult to injury. First my money was taken then I ended up with a negative.
