Have found reviews by users that have submitted several hundred ratings in one day (for several days) with the same comment, category, etc. listed..... in which it appears that a automated tool was used to leave ratings. How can one person rate several hundred websites in one day and be able to formulate an accurate opinion of that website. Makes me wonder about the validity of WOT when suspicious activity by a user like this counts as a rating. Thought WOT would be a good tool to judge sites...but not so sure now.... who knows if a rating is legitimate or a product of automated rating tools used to mass submit +/- ratings. Reply to Sami's response below: Thanks for responding Sami.....However the link you provided doesn't explain how manipulation is prevented....only that is is "very resistant to manipulation". Which to me sounds like it can still happen. And in my opinion is has. I do not understand why some chosen users are allowed to use mass rating tools for sites that they do not have any personal experience with and possibly have not even visited. It also seems that because of the use of the mass rating tools and higher rating numbers...their rating is weighted more. So for example, several people could have great experiences with a website...and then someone with high rating numbers and using mass rating tools comes along and gives a site a bad rating...now that site has a bad reputation. I believe that everyone's rating should carry the same weight. There is one site that this happened with and I know for a fact that it is not a "scam site" as I know that owners and have done business with them for multiple years now. Other rater's have given this site great ratings because of their experiences...then came along the mass rater with a heavier weighted score and because of his score the site no has a "bad reputation". On this mass rater's WOT profile, his motto is in quotes, "To anger some nerds - priceless. For everything else, there's MasterCard". Doesn't seem like he has the best intentions when using your mass rating tools...does it? In a nutshell....It's my opinion that rating's should be per that person's experience with a site and should carry the same weight as everyone else's rating. Mass rating tools should be avoided as it's very easy for someone with bad intentions to ruin a site's reputation with these tools. I use the think that WOT was a very reliable way to view a site's "reputation".... and I still think it's partly true because there are people out there that are honestly rating a site based on their experiences. But with tools and weighted ratings being used.... it definitely makes me think twice about the WOT rating/reputation for a site.
