Is there software or a website out there that I can feed a list of pages w/ my backlink on it and it'll give me back a report if the sites are blocking link crawling via nofollow, robots.txt, java, etc etc... ?
I wrote an article on Checking for No Follow Link. It explains the difference and has a link to a script that you drag to your favorites and it will highlight any links that are no follow. You can also check the source code but the method in my article is much easier. You do have to check each page one by one though.
You can use the plugin SEO for Fire fox, it actually marked the nofollow link with red or a color of your liking.
