Imo if a mer doesn't review then the problem wasn't big enough to warn others about. I reviewed regardless of the behavior of the maker. I can even say if there was only a few small problems I wouldn't have reviewed either because it's not worth it. I wouldn't post a good review either if I wasn't happy enough to. If I was happy, I would post a good review and mention any issues I saw that aren't that big of deal. People should say something when it comes to big money investments.
