I'm not judging you one bit. I don't know which sites you were referring to, and you're clearly taking the nice-guy approach. But there are arguable reasons to not remove content just because someone is embarrassed of their past self.
Also I wonder if in the future lawmakers will put mechanisms into place that regulate information and give individuals the right to have their records deleted.
That's already happened in some places.

Let's take two different examples: facebook vs HN.
If we're looking at facebook then someone would have a really good case to have their account and all data associated with it removed if they asked for it. In some places that would be legally enforceable.
In the case of HN I think the contributions are woven in to the site so strongly that other peoples stuff would be negatively affected. In such a case I would propose to anonymize the writer.
This avoids the embarrassment but leaves the fabric largely in tact.
"I'm Google Blasting myself!"
Huh? What the hell is that?
"Well you see, I need to stop having all my online activity appear on page one on Google when people type in my name. So I paid this company to clog Google with a bunch of fake, generated content about me. Hopefully the real information about me which I want to hide from casual searchers will be drowned out in the fake information."
I had never heard of Google Blasting for the common end-user before this, but it's a brilliant idea. And I bet as all of our lives end up being more public through Google, Facebook, Foursquare, etc, the demand for services like Google Blasting will grow. It sounds like a great business idea, though the timing is still wrong, since we're at least a few years from reaching a mass-market demand.
Ultimately, I disagree slightly with Gibson saying We never imagined that artificial intelligence would be like this. We imagined discrete entities. Genies. Simply because it will be far too easy to spam and blast this form of AI.
True AI in the sense of Wintermute/Neuromancer will happen, inevitably, just not yet. And the day it arrives, Google is instantly dead, a relic of a past era, an antiquated technology we'll all smirk at in history books.
in case anybody is interested...
