If the content is there but is not accessible (findable) then it may as well not be there. The Internet is content farms and SEO spam strictly because that's what can be found and accessed by the overwhelming majority of people. A non-indexed blog or site, or one that is sufficiently low on the results list, may as well not exist. It's like farting when you're home alone. You farted but nobody but you gets to enjoy the intestinal perfume.
