You misunderstood. What I said was that I have a few websites with all links pointing to them coming from purchased text ads, yet those websites still rank fine. Am I to assume that paid links are OK by google, since I have websites ranking solely through them?
Whatever the original intent of nofollow was, fact is that google lists paid links as one of the examples in their guidelines for using it, the other being websites you don't trust.
Bottom line is that nofollow has no positive effect for the webmaster, why risk any possible negative effect, however small it may be?
