many of the URLs in the "blocked by robots" list aren't actually errors, the webmaster purposely blocked that access
One would like to think that none of them are errors and all of them were blocked on purpose ;)
Maybe g### could steal an idea from Bing. They've got an extra flag that means "Did you really mean to block this? We think it's an important page."
