That's right peter112! I agree with you it would push the seller to improve without causing harm to their rating.
Noisychain, only in the art business people would attack the buyer for not knowing what to do with the product they ordered. In every other industry and business we always start from : (The client or buyer is always right).
The reason for this is that cash is king, it is a buyer's market and in the end if the buyer is not happy we loose money.
So it does not really matter if the buyer or our client is complaining. We have to make sure they get what they want or give them a full refund so they can get what they want somewhere else.
These are the basics of all business and really should be taught in art schools.
Honestly this is also why artists have such a bad reputation in business.
If we do not accommodate the clients the way they expect us to they will just put their money somewhere else.
Just basic economics, business strategy and why art is not a very profitable industry and most art schools should be shut down for not teaching this.
