WOT's ratings are certainly derived from user input, but Norton Safe Web and SiteAdvisor take a different approach. SiteAdvisor uses an automated testing system for websites based on behavioral analysis, or something similar. There's a technical White Paper somewhere on the McAfee site if you're really interested, but it's a long and technical document... those user reviews on SiteAdvisor pages, though, don't count towards a rating. They mostly seem to be for letting off steam by dissatisfied customers :-) Fun to read, sometimes, but mostly pretty repetitive and dull. Norton SafeWeb must use something similar.
