I used to leave positive feedback as soon as I shipped an item. A week or so ago, someone new to Ebay left me negative feedback claiming the card was fake, which it was not. Because I had already left positive feedback, I couldn't counter the claim. And Ebay could care less because they refuse to do anything about it. So my perfect 100% feedback has been tarnished because someone idiot posted false negative information, and Ebay does nothing.
