As first reported by GrayWolf on his blog, the US Olympic Team sells text links on their website for sponsors. They pass page rank and are DoFollows. Interesting?
I have to quote Michael Gray- he said it best “Now I’m not daft enough to believe that any of those companies gave money with the primary goal of getting a link, but at the end of the day no matter how altruistic their goals may have been, this implementation clearly doesn’t match with google recommended implementations.

The selective an uneven application of justice and rule enforcement is one of my major problems with the big G.”

…and finally I must add in this “What is good for the gander must be good for the goose - Google.”
