&gt; Why should I write a review? I have nothing to gain.<p>Unfortunately I&#x27;m now of that mind-set as well.<p>A few years ago I was in the top-500 of reviewers on Amazon UK, based on &#x27;helpful votes&#x27;.  I only reviewed things that I had bought for myself and focused on items that had no or very few existing reviews.<p>Then two things occurred quite quickly:<p>1. I learned that many top reviewers were receiving free samples as part of Amazon Vine.  I asked myself: why am I spending my time doing this without recompense?  They were churning-out multiple reviews per week and I was doing perhaps three or four a month, but it still felt unfair.<p>2. People starting aggressively scoring reviews negatively for subjective reasons.  I remember an airline stewardness marking as &#x27;unhelpful&#x27; my review of a book because she said I had insulted her airline.  Amazon weren&#x27;t interested in reverting down-votes like that.<p>I drifted away from Amazon reviewing after that and in time I have also drifted away from Amazon.  They never fostered their community of honest-amateur-reviewers ( with, say, a Gift Card at the end of the year ) and they&#x27;re paying the price now.
