"user" reviews are all over the net including those that sell products. You will often find a couple of bad reviews for every product and suppler. If a couple of bad reviews killed a product or vendor, no one would stay in business. The other thing is that a bad review for a good vendor often finds a lot of satisfied customers coming in to support them. If a site were liable for posted reviews, a lot of sites would be gone. I have both good and bad posts that I would add for pond contractors, but these are just my opinions.
