It is by and large, a great site. It serves to protect you from hate filled and malware ridden sites, and it seems to do the job. Ratings will however be swayed by the opinions of its users.
My only major problem, is this "only for kids" and "How suitable is the website for children?". Who are they to bloody decide what kids can and can not use or are not suitable for?
My only gripe is that the moderation of comments (and maybe some of the ratings which contradict the nature; look at tucows or some websites which clearly host malware as an example) on MyWOT could be better and should really remove the rating system for the comments as they pose no use, it should be a 'trust' or 'don't trust' value for comments.
