It's weird that there some subtle defensiveness here. To heck with robots.txt and what not, when a site touts it's privacy, even this, however irrelevant, is slightly eyebrow-raising.
How does this in any way reflect on either the privacy of DuckDuckGo (I don't think they ever claimed or even vaguely implied that if I search for, say, Banana, no one else will be able to see the results page for Banana, as that would be absurd), or Google, who are simply indexing publicly accessible pages, which is what they've always done since coming into existence.
What violation of privacy or hint thereof is happening here?
None. Thus my question of why the Curt responses and passive aggression. DDG has positioned itself as the anti Google and lo and behold Google still finds out what's being searched there, though not necessarily who searched it. If you're a bit cynical, it's vaguely interesting.
