I think it's a bit of a catch 22. Ebay changed their policy from allowing sellers to leave negative feedback to banning it because when a buyer would leave honest feedback netural or negative the seller would often retaliate by leaving negative feedback for the buyer, so buyers simply either didn't leave feedback or didn't leave accurate feedback which made the ebay feedback system inaccurate because they were worried about retaliation.

I not too long ago purchased a signed photo that was significantly blurry however that detail was not listed in the description and was not visible in the picture of the listing. There were a couple of other issues like too expensive given quality (which I didn't know until I received the item) and an illegable COA. I sent a very polite email the seller but he ignored me so I left a honest feedback listing positive and neutral comments. I thought I was generous in that (I didn't say the item was in fact crappy) however the seller didn't like what I said and left me a somewhat neagative comment criticising my communication skills and saying I didn't know what a COA was. He also sent me a not so nice email to accompany his feedback.

I didn't report him or open a dispute for a $60 item because I couldn't be bothered. I will however never buy from this seller again.

I would also like to add I have experienced far more positive experiences on ebay than negative.

My point is this if this seller had been able to leave negative feedback he would have left it for me when I did nothing wrong.

I am not a seller. I think on most occasions it's good that sellers can't leave negative feedback however I also think in the case of non paying buyers (when provable) an exception should be made to this rule.
