Moderation by voting for or against a site is fine in principle, but in practice there are just too many sites and too few votes. Aside from the really high profile ones and the webmaster-relevant ones (e.g. dmoz), how many sites in Alexa have a review and rating? Very few - and of those, almost all have between one and three votes. Easy for the webmaster to promote their own site - that's why the Alexa stars system is currently meaningless.
