In looking carefully at favorable reviews on 2 of the sites I found that very glowing reviews were made on the same dates. In one instance 9 extremely good reviews on one day.
Even on the most active sites you are lucky to get 2 reviews in a month, 9 on one day on that site and similar activity on another indicated to me that a poorly rated firm was putting in, or having posted, bogus reviews and those comments are not added to this site.
