Some curious things about DuckDuckGo search engine.

I thought I could use DuckDuckGo as a neutral search engine to moderate a series of queries from Google and Bing.  Instead, what I quickly noticed was that DuckDuckGo's results placement were eerily mirrored by Bing.

Search for "macadamia nut pancake mix" results:

Google DuckDuckGo Bing
amazon.com konacoastpancakemix.com konacoastpancakemix.com
worldmarket.com nextag.com nextag.com
mezzetta.com amazon.com amazon.com
konacoastpancakemix.com siphawaii.com siphawaii.com
abcstores.com worldmarket.com worldmarket.com
siphawaii.com simplefoodie.com simplefoodie.com
shopwell.com thefind.com thefind.com
simplefoodie.com honestcooking.com honestcooking.com
walmart.com abcstores.com abcstores.com
minimalistbaker.com hawnnut.com hawnnut.com
sugardishme.com rover.ebay.com rover.ebay.com

That's an impossible coincidence for a relatively obscure search, don't you think?  And I've replicated this many times, now.  It seems to me that DuckDuckGo is using Bing.  If you look carefully at a sidebar ad, it says that DuckDuckGo was built "in partnership with Yandex" -- a European (Russian) search engine. Only problem is that a similar search on Yandex does not replicate the same results as on DuckDuckGo's results.

So I'm wondering if DuckDuckGo licensed Bing, and if they did so, are they passing IP addresses as well as search terms back to Bing?

Secondly, I think someone needs to clarify why DuckDuckGo utilizes a handful of single pixels in their search results, some of which change its URLs with each unique search.  Usually these single pixels are done so, as a work-around means of tracking people without using cookies.  I find this very troubling.
