ReviewMeta
Here are just a few examples:

However these sellers are essentially stealing old, expired listings of products and collecting all the reviews associated with them to pump up their rating and review count.
This has been going on for over a year. I really don't understand how Amazon hasn't figured out a way to close the loophole at this point...
We all can look at reviews and make our best guess, but at the end of the day, it's always going to still be a guess. At ReviewMeta, we aren't claiming to know all the answers. We try our best to ensure everyone knows it's an estimate (you're actually forced to click an I agree button before accessing the site) and we also provide all our work so you can use the numbers to help you make a more informed decision.
Technically speaking, of course ReviewMeta can be "gamed", but it would require much more effort on the part of the seller to generate reviews in such a way that it wouldn't set off any warnings on our side. Basically force them to be very deliberate in their efforts. It would just add yet another hoop for sellers to jump through, making it that much more difficult on their part.
The first example is a little trickier since the first time we analyzed the product, the title had already been changed. (You can click on the "Title History" link for any product).
We're working on being able to detect when these changes/variations are normal or being used to deceive shoppers. It's extremely easy for a human to immediately tell, but much harder to train a computer to do it. For example, a seller might have a t-shirt with different product variations: "Large Blue", "Medium Green". These are very different words, but obviously a legit reason to have a bunch of variations.
