While this site is designed for businesses and professionals and not for children. It certainly doesn't have anything on it that is unsuitable for children. I would have no concerns at all if I came home and saw a child on this site. Though I would perhaps wonder if my child was a closet genius and trying to start the next Fortune 500 company. :)
This rating appears to have been spiked by a competitor. The company is credible and ethical, the business is sound, the service is excellent. There are no comments to support these poor ratings. By allowing this unsupported downgrade to persist, WOT is performing a disservice to itself - it makes me wonder whether other Poor's I've seen from WOT are actually valid.
