For their own purposes and to protect dishonest sellers. I was once an avid EBay shopper, but now avoid EBay. Buyer protection no longer exists. You buy at your own risk.

On my last feedback encounter dealing with my purchase of tools from one of their merchants selling defective items and then stealing my credit card information to try and get funds, I posted a negative feedback. When I went to check on that feedback, ebay posted it as positive. Again, Ebay/ Paypal are a den of thieves thriving off misrepresentation of products either stolen, or not correctly advertised. STAY AWAY from ebay and paypal unless it is absolutely clear you have a recourse with your credit card to be reimbursed. My card carrier has informed me they are aware of ebay and paypal games today and their merchants. I felt so violated when paypal gave the unsavory merchant my card information so they can try to run it through another store front! OUTRAGEOUS!

I also was once a heavy shopper of EBay. I agree that buyers protection no longer exists. I will pay retail price before I purchase anything else from eBay.

Ebay violates so many of their own rules it's enough to make your head spin.
That is why quality sellers are leaving in droves.
The poor buyers are stuck with who-ever is left.

You really have to know what your doing when you shop anywhere, store, website, yard sell, etc.

Unfortunately there are also unscrupulous buyers. I personally know of people that have received goods but claim they never, thereby getting goods for free. That's one of the reasons seller's have left eBay.
I've been an eBay buyer, and sold a few bits, for over 10 years. I've never had a bad experience because of eBay, but I have with faulty goods purchased. They work initially then fail at a later date. Feedback has already been left, so no recourse through eBay.
PayPal have always refunded my money when goods were not received, BUT,... and I say BUT very seriously,... if you've received the goods and they later fail, within the 60 day PayPal guarantee, they don't want to know. Instead they wash their hands of it and tell you to sort it out with the seller. Consumer laws in the eu state you're entitled to a replacement or money back, but that's ok if the seller is local, and not if they're in another eu country.
Who's going to chase them through the courts? Who has the spare cash to do that?
Unfortunately sales are down on eBay, and they're letting $#*! sellers continue to trade.
And it's no better on other sites such as aliexpress. My wife bought a dress from a seller there. It arrived, it was crap. She posted it back. The seller said they never received it, and my wife never got her money back. So it's the same the world over.
Let's face it,... most of the $#*! we buy is just that... $#*!! Produced in China by kids in sweat shops or adults on crap money. Do we really need the crap? NO, we want it.
I've come to the conclusion that buying this crap is a futile task. I now no longer will buy "things" I want, because I don't need them.

Ive had a seller offer a partial refund for messing up my order. When i declined and wanted a full refund that Ebay "guarenteed" I got denied... even though the seller admitted he was wrong and was offering a partial refund... this company is complete garbage.

They do so because as they told me, "they do not want to discourage or scare away buyers". And therefore you cannot post negative feedback however now what people (both buyers and sellers who have a bad experience) do is post negative comments in the positive area. Read this feedback carefully.

Ebay will only remove feedback (if one of the established guidelines is violated) they wont change it to positive!
I am disappointed with Ebay, my sales have gone down since the Google fiasco.

Idk but my purchase from them was fine
