Anecdotal data, but for some of our products we sell, only such "unfair reviews" ever received comments from other shoppers (either pointing out the mistake, or straightforward ridiculing of the reviewer). I have a mixed opinion on it in regards how it affects customers considering our products, since one to have to make an effort to go beyond stars-value. But on the personal level it certainly makes me feel better (almost as much as handwritten thank you cards =))
