I had a similar experience. I've shared it before but I'll copy it here: I've stopped leaving Amazon reviews. Recently I was bored and went through a few bits of network equipment and PC hardware I purchased and reviewed a few of them. 3/6 of the reviews were rejected for being against community guidelines with no reason provided. Even after reading the guidelines it's not clear why they were rejected. I put in effort to describe why something got its rating from me. For example, I discussed the strengths/weaknesses the network equipment. From now on I might leave a star rating, but I'm not wasting time to get a review accepted. I'll leave that to the shills.
