I'm not too sure who is familiar with Web of Trust, so I'll start with a brief description. It's basically a browser app that inserts a circle next to text links in websites. The color of the circle indicates whether or not it's average rating by users rates it as having a "good reputation" (green) or a "bad reputation" (red). There are four criteria: Trustworthiness, Vendor Reliability, Privacy, and Child Safety.
Singularity.org's printout is here. As you may have guessed from the title, Web of Trust lists Singularity.org as "poor" in trustworthiness, vendor reliability, and privacy. There's a comment that, when translated (via Google translate) says "Mass mailing of non-thematic Forums". It's also commented under the category "malicious content/viruses".
I'm not entirely sure how these ratings are generated, (How Ratings Work, related) but I've used it for several years, and this is only the second time I've disagreed with a rating. I've always found WOT to be very reliable, and a decent way of warning me if a site is unsafe so I don't have to think about it. So I was fairly alarmed when I saw the red circle there, since I'd imagine it's turning away people that don't know any better. If LW had a red circle, I never would have come here. I'm not sure what SI or LW can do about it, but there's a "click here if you are the owner of this site" button, although I don't know what that does. I've left my own rating on there, but it didn't seem to change the overall rankings.
Edit: When I made this post, the scorecard read Trustworthiness 30, Vendor Reliability 31, Privacy 31, Child Safety 100.
Thank you, but it seems the problem was already solved. At this moment, both "verify1st.com" and "mywot.com" give Singularity Institute website high ranking.
My guess is that the original problem was simply caused by not enough ratings; probably zero or one positive ratings and one or two negative ratings. At least one negative rating and comment was by a very religious person, who by their voting history seem to automatically give lowest posible ratings to anything in conflict with their religious views. (That's my complaint against the whole Web of Trust system: regardless of official criteria, most people will use it as a Like/Dislike tool, giving either highest positive or highest negative ratings.) Adding a few positive ratings seems to have fixed this problem.
