No doubt you've already heard the stories of the appalling way Amazon treats its staff and prevents unionisation, its patent on the obvious 1-click purchasing feature, killing off local bookshops, remotely deleting paid content from users' Kindle devices, its terrible track record on pollution, anti-competitive operations, treating LGBTIQA+ books as "adult content", and squeezing sellers. Well now you can add "deleting reviews that are unfavourable to racist and misogynistic pseudoscientific authors" to the list. I'd been a customer for about 18 years, used most of their services at different times, and had written many reviews, almost all of which had many "helpful" votes attached to them. And it was me who convinced my family to get Amazon accounts. I dread to think how much money I've put into Bezos's back pocket during the last 18 years or so. I then left a review on the worst book I've ever read in my life pointing out some of the myriad problems with the it. A few months later it was deleted with only a perfunctory notification email with a broken link to their guidelines. No mention of which review or why, I had to sit through a 35 minute chat with three different "customer service" representatives to try and find out why, and all they said was they would email me. I then had to have an email exchange with someone else to finally get to the bottom of the issue. Long story short: Amazon don't allow customers to leave "spiteful" reviews. And, apparently, calling a racist and misogynistic pseudoscience book exactly what it is will be considered by Amazon's employees as being "spiteful" towards the author. Their various one-line responses were all signed with "Your feedback is helping us build Earth's Most Customer-Centric Company." I think maybe someone needs to explain the definition of the words "spiteful" and "customer-centric" to Amazon. Based on these interactions it's clear that only positive reviews are allowed on Amazon. I've now deleted my Amazon account and will be taking my Kindle to the local CEX shop to exchange it for a Kobo tomorrow. I'd like to congratulate Amazon on having the absolute worst policies of any company I've ever had to deal with (vehemently defending dead, racist authors) and the absolute worst customer service ever to boot (pushing long-time customers directly to their competition). Well done Amazon, well done.
