---- PR Sculpting Doesn't Work and Internal NoFollow Can Harm Your Site

These people who post listings, just copy and paste on each site. They are duplicate pages on hundreds of sites. So whether they should be nofollow( noindex also) or they should be allowed to be indexed and treated as supplemental pages.
I'd let them stay indexed and dofollow. I assume there is some internal navigation on these pages, right? If so it sounds like a lot of PR circulation that I wouldn't want to cut off. Have no concern about a duplicate content "penalty" - there really isn't such a thing for a case like this.
