What's the purpose of publicly posting a less than honest review? Some may post bad reviews about their competition I suppose and of course there are those who will post fake reviews about themselves to boost their ratings. But if it's a legit review, there's no reason to not be 100% honest. Let them know what they did wrong. If they hold enough value in the review system, they will correct the issue. If not, they won't and they will lose business over time.
