My favorite Amazon scam is the Amazon Ship of Theseus[0]. You sell a product, normally a cheap electronic, and build up a decent corpus of positive reviews. A good example is a USB-C cable or something. Then you decide you want to sell a new product in a more competitive subcategory, like Bluetooth Headphones. You then take the _existing_ listing and change it piece by piece. First the pictures, then the title, then…
As annoying as scams like these are, they really speak to the ingenuity that folks bring to software and their attacks of it. I already know to not trust most things on the internet, but I can't help but admire them either.
