Being able to leave a negative for a buyer doesn't serve any purpose because it doesn't stop them buying. Having non paying strikes against them CAN stop them buying.

I think my bad experience buyer tried to treat me like I was a business, you must do this, you WILL do that, did you know and if you don't, you should, all that kind of stuff. I was so happy when I was able to close my non payer dispute and get her off my back. It did leave a bad taste in my mouth.

Like you, I see myself as being honest and forget that not everyone is like us. There are people out there that try and take us for a ride. They make a hobby out of trying to rip people off. I would never deliberately try and deceive anyone, yet that's what I was being accused of and it did rattle me up a bit.
