nofollow gold

When I scrape backlinks to analyze a site I often wonder if there is a tool that will only scrape nofollow backlinks? The idea being to check for PR sculpting errors that block valuable content. Has anyone seen such a tool, or willing to share a technique? Gracias.

Use the No Do Follow plugin for Firefox, available here
It will highlight links in a page according to nofollow / ******** status.

Activate No Do Follow on your target page.
Copy and paste ALL the links on your target page
into a WYSIWYG html Editor, like FrontPage
or Komposer.

Delete the do follow ones that the plugin showed you.
View the page in the HTML or Source view to see what's inside.

Until we can find software to make this easier, that's one way to try it.
