Is mywot.com Safe?

This is potentially useful, given that everyone who evaluates this site is honest in their ratings. I'm concerned, like others, about the use of the scorecard to voice their personal opinions, rather than to inform other of whether or not the site is a) trustworthy, b) reliable (for vendors), c) not intrustive to other people's privacy, and d) safe for children. Sound familiar? Also, I don't like the idea of one overall score; in other words, it's misleading to see a green circle for the overall site when one category may be green and one other is orange/yellow. Lastly, I do worry about people who abuse this site by spamming the comment boards and giving random ratings to different sites. It's hard to trust users' opinions sometimes; sometimes you find that the rating makes no sense. Of course there's more concerns, but all in all, I still use this site with caution; I go to other resources for more information about a website. Web of Trust is a great idea, but I think it may still be quite flawed.
