> DuckDuckGo distinguishes itself from other search engines by not profiling its users and by showing all users the same search results for a given search term.
Also note that DDG doesn’t just rely on Bing.
> DuckDuckGo's results are a compilation of "over 400" sources, including Yahoo! Search BOSS, Wolfram Alpha, Bing, Yandex, its own web crawler (the DuckDuckBot) and others.

Anyone can see this for themselves by comparing a number of Bing and DDG searches.
