---- Pages are indexed even after blocking in robots.txt

so it helps to "nofollow" links to pages you do not want crawled
I do not think this is a good idea. a) if the page is not crawled, the robots noindex will not be seen b) in any case, nofollowing the link does not stop Google crawling the page. c) nofollow will stop natural page rank circulation within the site and PR will go in the "black hole"
