Earlier quoted context omitted.
Your comment made me go lookup my old reviews. It's crazy, most of them were deleted. I would have expected to receive some kind of notification. I thought I could sift through the rubble to discern fake from real but now I know Amazon reviews are absolutely worthless.
Wonder if we could make a browser extension that stores and presents amazon reviews. Could be useful to fill gaps on other sites too, for example when an uploader turns off comments on youtube. It would be a pretty big middle finger to amazon if the primary site for amazon seller reviews was not actually amazon, but a third party site/app.
It's possible in technical theory. But sharing the comments would be hard. Federation might work. Spam moderation could be hard. And most websites refuse to go into iframes, so your options are limited to browser extensions, SOCKS proxies, and Opera Mini style apps that re-render the page. Which means you'll get less than a percent of a percent of people to use it.
