Now now, I think you're the one being disingenuous. Google's algorithm is not "everyone elses problem". If someone doesn't care about what appears on search result pages, they can just ignore everything search engines say: all their guidelines, all their advice, just chuck it out the window. Your website will still work fine.

This blog does not indicate some fundamental breaking of the web. It indicates a guy got a random email from a random website, that he is free to ignore if he wants (and in fact should ignore, because the webmasters in question don't even need to contact him, they can use the disavow tool).

No work to do? No problem!
