Danae, I believe the term Robots is a misnomer, there is a robots.txt file, or a simple code snippet used to tell a web crawler (google cache, archive.org, etc...) to not crawl a given url or domain. I can look into the proper term(s) further if you like.
That is pretty much exactly what Leo found. As far as I know, it is an accurate description. If Justia goes to remove itself off of InternetArchive.org, that would be an admission of guilt. And believe me, we are watching the archive to see if Justia puts up mor of them on the pages we have published today, and the ones Donofrio has published at his site: http://naturalborncitizen.wordpress.com/2011/10/20/justia-com-surgically-removed-minor-v-happersett-from-25-supreme-court-opinions-in-run-up-to-08-election/
