Wikivoyage has disappeared from DuckDuckGo
From the article -- <i>What concerns me is how obscurely the results have disappeared from three search engines, which also happen to command a fair share of the market after Google.</i><p>What the author really means is "they have disappeared from the only other English language index in the US." Yandex, an English language index hosted in Russia returns the wikivoyage queries as expected.<p>If I were to hazard a guess (and I am guessing here) the answer is here (also in the article): <i>The first result links directly to Wikitravel. Wikitravel is the original project and a schism in the project resulted in the creation of Wikivoyage, ...</i><p>Based on this piece of information I would guess that Wikitravel sent Bing a DMCA take down notice telling them that Wikivoyage infringed on their copyrighted material. And as a result Wikivoyage was de-indexed from general results.
