That’s not true.

DDG has their own crawler and their results are a composite of many different sources of which Bing is one.

It’s easy enough to check. I searched my name on both DDG and Bing, the results are completely different.

While they do have a crawler (DuckDuckBot) they primarily rely on other search engines the main ones being Bing and Yandex.

The fact that they return different results doesn’t mean much, firstly the bing API and web search return slightly different results especially if you use some of the extended parameters, secondly it doesn’t mean that they return results without additional post processing since they can have their own weighting/pageranking algorithms, filters etc. on top of Bing.

DDG isn’t just a UI for Bing but their results rely on Bing.

Search for "what is my ip" and you will see Bing bot IP in the DDG snippets.

> To do that, DuckDuckGo gets its results from over four hundred sources. These include hundreds of vertical sources delivering niche Instant Answers, DuckDuckBot (our crawler) and crowd-sourced sites (like Wikipedia, stored in our answer indexes). We also of course have more traditional links in the search results, which we also source from multiple partners, though most commonly from Bing (and none from Google).

In other words, their own crawler and the other 400 sources are used for their Instant Answers and widgets while all "traditional links" (i.e. the search results) come from Bing.

I do believe your main point is correct, however your easy check doesn't prove it.

Even back when DDG did only use Bing/Yahoo data, you'd likely have seen different results for your name depending on what personalised results Bing/Yahoo might show you, or other aspects (such as weighting applied to your location).
