Bests & Worsts Reviews from Amazon

I do a lot of product reviews and I purchase a lot of stuff here on Amazon. How do I know mostly of the 5 star reviews are fake? Easy... 1-click on "customer reviews" 2-Sort them by "newest first" 3-Right after the reviewer's name there is a link that says "see all my reviews", here you will see they have only reviews 1 product, theirs!. Nobody else's 4-Go on check the people that actually REALLY wrote a 2,3 or 4 star reviews that go really in depth. Click on their "see all my reviews", here you will see they have reviewed other products in the past. Those are legit! 5-I actually own a Foscam FI8910W and actually like, I'll write my review tomorrow. 7-Foscam, stop buying "customer reviews" from external websites that offer that service (yup, just did some research on this), or telling your employees to to post fake reviews. This is really dishonest as a lot of people rely on honest reviews to make their purchases. 8-Amazon, reviews should only be aloud for "verified purchases" only, that will greatly minimize these fake reviews.
