I agree with the essence of the discussion, But am against negative feedbacks to buyers. I am a seller my self but do not advocate same. Reason being than buyers do not have level playing field. In case co-operation is not being done by seller even than buyer cant leave a negative feedback , fearing counter negative by seller. Also sellers may use it to their own advantages in many similar ways.
What sellers need right now is Protection from new buyers who do not have any idea about the feedback policy and the DSR's. Something like Seller protection.
As mentioned many time before all of my negatives and neutrals have been left by buyers with less than 5 feedback score. this further proves my point.
eBay should keep a waiting period of 7 days for buyer to contact seller and resolve the problem before he leaves a negative or neutral. Like we sellers have this options-
Leave Positive feedback or leave feedback later, similarly buyers should be given options like- leave positive feedback and resolve problem. Option of leaving negative or neutral should be opened only after 7 days of reporting your problem.
This would increase buyer satisfaction level. As well as help us mention good report cards.
