I worry with a system like this that you could find yourself removed not because you provided bad service but because people think about the scale in different ways. On amazon for example 4,5 is considered positive and 1,2,3 negative. You really want to keep 90%+ positive. So when someone comes along and decides to give a 3 because they thought the transaction was good but nothing out of the ordinary it hurts you. The lack of nuance doesn't feel great either. For instance when you look though the bad reviews on trip advisor for a good hotel they are often people that have enlarged expectations of what the hotel could reasonably do for them. In some cases the hotel even going above and beyond couldn't please them.
