Fakespot analyzes Amazon pages and identifies fake reviews
This is pretty amazing. Fakespot is a website that lets you plug in any Amazon product page link and it spits back an analyzed report of whether the reviews on that page can be trusted. Very helpful when you can't exactly tell if a product has reviews made by automated bots.
If you like it -- and why wouldn't you -- there's a Google Chrome extension that you can install so it'll always show whenever you visit an Amazon page.
