Half the time the fakes are so ludicrously easy to spot that I really wonder why they bother.  Fifty glowing reviews of a book within a day of publication all raising the same 4 esoteric points in the review.  No doubt 4 points suggested by the author&#x2F;publisher when asking for the astroturfing.<p>Completely disregard all Amazon Vine reviews.<p>Now weight heavily in favour of reviews that have had update edits - &quot;it failed after 2 months.  The replacement failed 3 months after that&quot; (common on all makes of $200 LED gaming keyboards) or &quot;after a year it&#x27;s still in perfect condition&quot;.  Photos on the reviews are often a good sign too - but only when there&#x27;s just a few - photos on reviews are <i>rare.</i>  So lots with similar framing would be an instant strike.<p>Try finding a CAT6a cable on Amazon - seems they&#x27;re all 4.5 - 5* wonderful, yet dig into the bad reviews a bit and most of them don&#x27;t even meet wire or shield spec.  Even those coming from Amazon themselves.<p>Aside from reviews from specific, trustworthy people, reading the mid-tier and bad reviews gives a much better flavour of what a product is about, and the odd review tearing the product to pieces can be worth its weight in gold.<p>If it&#x27;s a marketplace seller my starting point is to mistrust all reviews and let them earn trust <i>really slowly.</i><p>I sure won&#x27;t be going near Fakespot, especially when they&#x27;re so intentionally vague in describing their own product - it&#x27;ll be a score to game like your Klout score and all the other meaningless metrics.  The astroturfers will adjust what&#x27;s needed in the fakes to pass.
