I've been trying to track down what the black hat seo people are doing to sell these so called "white hat high PR links" and came up with this document. What is interesting is if you see how the anchor text ranks in Google for some of the spammed sites you will see the sites are no where to be found. The result is this ends up being negative SEO campaign that an unsuspecting person actually paid to have done to their site!
I hope that more and more this kind of junk is going to go away. Meanwhile, I do strive to educate people about SEO. Building a site people live should be goal #1 always.
