Duck Duck Go partnered with [[The Parked Domains Project]], which regularly crawls the [[World Wide Web|Web]] and marks [[spam]] and parked domains; DuckDuckGo omits all domains marked as spam. The search engine also uses human policed sources like [[Wikipedia]] and [[Conservapedia]], placing links from these sources (note not just to them, but from them), above algorithmically generated links. The CEO, Gabriel Weinberg, explained, "We've gone out and found entries in about a hundred other human-powered sites that are policed for spam. We use their APIs and extract the info. [...] As a result, our links are doubly controlled for spam."<ref name=fast/> | Duck Duck Go partnered with [[The Parked Domains Project]], which regularly crawls the [[World Wide Web|Web]] and marks [[spam]] and parked domains; DuckDuckGo omits all domains marked as spam.
