Yes exactly we do not have any control over this content and this is copied on many sites at the same time. Moreover these pages are so many in numbers that they exhaust all quota from gbot and our other important pages are left behind. While putting them in noindex and their links in nofollow many of site owners were not even aware of PR sculpting. Their main concern is duplicate and junk content and feeding google with least important pages while ignoring more important pages.
