I agree with dethfire. It takes Google ages to process these no index and nofollow tags. I did this to a user generated part of my site and 3 months later Google still have them in the index.
Also there is plenty of evidence that even though Google says they won't follow the "nofollowed" link they still do but just don't use it in the ranking algo. Even wikipedia mentions this effect on it's nofollow page. Of course it is hard to prove this as there maybe sites out there that you don't know about that have a follow link to this particular page. However some of these experiments blocked everything but Google bot in Apache config when the test pages were published and Google bot still crawled those pages.
I personally haven't done these experiments, has anyone here done any like this?
