First, not all of those are illegal at all. There is a lot of bad stuff online that is still, sadly, legal. Second, even if some of it were technically legal, that wouldn’t help victims one bit because their attackers would have disappeared anonymously into the night.

But the real point isn’t that Google is at fault for any of that. It’s that Google hasn’t even considered the privacy implications of its actions. If an offline business were encouraging illegal and anti-social activity, it would be shut down as a “nuisance” even if it did not engage in any illegal conduct itself. Why do we not hold online businesses to the same standard?

And it’s not about “censorship” of search results (anyway, these problems apply across search, Blogspot, Youtube, etc). It’s about creating a system where privacy is respected by users of all of its products. Plenty of people have asked Google to allow victims to respond, or to give less weight to anonymous content, or to institute a dispute resolution process, or any of 100 other things that don’t remove things from the search index.

Half of your examples would be illegal, and rectified through existing processes. The other half could be fixed by just talking to the content authors.

It is not Google’s job to be sure that everyone looks good in search results.

On that contrary, that would be censorship of their search results, which is exactly the problem people had with them in China.

If you have a problem with what someone is saying or posting about you, don’t tell Google to hide it. Go talk to the author and fix your own problems.
