They haven't lost all value, but you certainly can't take them at face value. I always make sure to read the negative reviews, as others have mentioned. I'll also frequently look at the review history of any review that resonates with me one way or another to see if they appear to be a normal person or a paid shill. Amazon could probably solve this problem if it wanted since it has access to purchase histories, shipping addresses, and review histories for all accounts on its site. I assume that the problem of fake reviews isn't solved because Amazon doesn't care enough about it to take the necessary action and fix it. It may also help Amazon's bottom line to have a bunch of highly-rated products for sale, even if those ratings are fake.
