DuckDuckGo is a search engine. It emphasises that it doesn't track users, but was exposed as tracking all the sites its users made from its Android app in 2020. The CEO commented that "I want to be clear that we did not and have not collected any personal information here."
As of January 2018, a page from ISGP was the #8 hit on DuckDuckGo for the search term "Dutroux Affair". Several other search engines such as Yahoo, Bing, Yandex and Gigablast also included it in their top 10. By contrast, neither Google not StartPage returned any hits from the ISGP site in the top 100.
7th floor group
Wikispooks was #30 hit for the search term "7th floor group" at DuckDuckGo, which listed it at #30, in January 2018. This is an interesting contrast with Ask.com, Bing, Ecosia, Google, Yahoo and Yahoo).
Compromised by fact-checkers
A June 2020 search for Wikispooks on Duckduckgo, gave Wikispooks as the first result, followed by a "fact checker". A search on the independent media Off-Guardian gave a fact checker as first result, followed by an article from Off-Guardian. This would imply that either significant resources have been spent on influencing the search results, or that the management of DuckDuckgo has been pressured or taken over.
