The ebay Feedback system is now a total JOKE.
The ebay feedback system has changed DRAMATICALLY over the past 12 years since I first started on ebay. The current system where BUYERS can now leave negatives at will, and
SELLERS cannot do the same or retaliate via feedback to slow payers, abusive buyers, or even total maniacs is insane.
SELLERS can leave a positive feedback, or nothing at all - period.
A 'buyer only' on ebay CANNOT end up with anything other than 100% perfect feedback. No matter how much they abuse sellers, or lie and cheat and steal stamps each day by alleging shipments never arrive, and being auto-refunded by paypal. So they get them free, and SELLER bears all cost - shipping INCLUDED, in their new insane policy.
When ebay finally catches them (and it takes months) they just start up another account and do it all again,
and KEEP all the stolen goods.
Like the insisting on PayPal nonsense, continually rising fees, and hiding bidder handles, and allowing 50 accounts to one person, as per several stamp forging gangs we have exposed, etc, it will contribute to ebay's eventual demise.

No serious successful stamp dealer
needs ebay at all - I do not notice Richard Juzwin bothering.

The final value auction fee on ebay now when paypal fee is added
is OVER 10%. For virtually everyone. This is the reason savvy sellers do not offer quality material on ebay a lot of the time - all
major real stamp auctions will gives you a better vendor rate than that.
In the early days it
was a transparent venue to buy and sell, and the feedback system then actually reflected the member's past actions.
For honest sellers the constant stupid rule changes erodes the usefulness of it every day.
ebay changed it to make more bucks, and they will pay the price eventually. Their fees were a couple of % - and now they charge more than most mainline global auctions to sellers.
