While this service has good intentions and I do like it, I believe that in some instances the people rating sites lie in order to defame a competitor. And questionable sites rely on friends or associates to rate a site as good and reliable when maybe it itsn't. So the site rating is only as valid as the perception and honesty of the raters. I may be stating the obvious here but the more ratings a site has, the more likely the validity of the rating.
