It shouldn't be Google's responsibility regardless. If there really is a defamatory article on some website, you should take it up with the source hosting the content, not search engines.
Are you referring to my last paragraph? That's not what I was saying. I was not talking about links in search engines. I was referring to say a Google user with a Google account wanting data Google has, in regard to their account, to be wiped. Replace Google with Facebook, etc depending on who the user had the account with. Like I said, that's not what this is about though
Oh I totally agree with that, I wasn't referring to your last paragraph. I think there were some efforts a few years ago on that front but I'm not sure if anything came of it. http://ejlt.org/article/view/75/144
