No thanks. I might just as well use Bing then since that's where DDG get its search results.
Do you have a source for that? DDG has their own cralwer[1], so it would appear it also gets its own search results, even if may get some search results from other search engines. [1]: https://duckduckgo.com/duckduckbot
> In fact, 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 source from Bing, Yahoo, and Yandex.
So DuckDuckBot is not used for any normal indexing. All actual search results are from Bing, Yahoo and Yandex.
