Just a quick thought on "review sites" in general from me personally.

I usually won't register for an unknown site just to write a review of something but if I'm on a site that allows me to write the review by just using my name and website URL and captcha I'll write a review of a product I like or dislike. However I'd imagine SPAM posts would be a huge problem for a site with such a simple process requiring and admin feature to approve reviews before showing them on the site (which isn't difficult programatically it just requires lots of time to approve posts).
