Ratings come from users of the WOT browser extensions. Users are able to rate sites based on their personal experience with them. Sites with poor reputation yield warnings from the extension upon later visits.
If no one has rated you, your rating will stay positive, or neutral, until someone does.
That's what I expected. Like I said, my test site wasn't "neutral", it was clearly rated positive on vendor reliability and child-friendliness. So what it boils down to is that someone arbitrarily gave taketake.com a very negative rating, not necessarily based on anything real. I'm not saying it may not be justified, but this kind of reputation system is clearly very flaky and prone to manipulation.
