Project Farm did a great episode on counterfeit tool batteries [1]. If I remember correctly, both ebay and Amazon were culprits, at least in the comments.<p>I personally find that one of Amazon's main affronts is interfering with customer reviews in order to maintain artificially higher ratings. For example, my reviews stopped processing and would never post. This happened after leaving honest critical reviews. Note that +90% of my reviews are neutral or positive. Additionally, they removed my ability to search reviews, replacing it with Rufus, a completely incompetent and worthless search bot. This, I believe, cleverly prevents prospective buyers from accessing useful customer feedback or experience unless the buyer is willing to manually parse all reviews, which ain't happening.<p>Amazon does a lot to convolute reviews, including jumping to the wrong review after selecting a product to review from the order history.<p>It's an extremely useful and convenient resource, but thoroughly rotten. The algorithms are flagrantly evil and a very deliberate and specific search for a high-end product, the desired product will often be displayed below several or many more cereal-box quality products worth less than their packaging.<p>Where they win is shipping, variety and pricing.
