No......Feedback is extremely important.

Being able to view a Buyers, or Sellers feedback is essential to gauge if you will be secure in doing business with them, and if you are likely to have any problems in trading with them. Also feedback is a good indicator of the professionalism of your trading. How many times have you seen someone get bad feedback, and then go on the defensive, using abusive and derogatory language? Instead it should be used to make corrections and improvements to your service as a seller. So in my opinion feedback is very useful.
