In most systems that do this, my 1 star review is countered by another 1 star review. I had a contractor fail to do the simplest possible task (write a XML layout for a login screen). Gave him a 1 star. He threatened to give me a 1 star too if I didn't change the review, and did so as promised. However, I have seen owners explain that certain reviews were part of a targeted attack to damage the owner's reputation, so I think it's the fairest approach.
