At this point, DDG is basically Bing, which heavily regulates piracy. Most often searching for a list of scrapers won't even result in a search return. I know 1337 is pretty blacklisted.
You should be using something like yandex.com for your search queries as they are one of the last ones I've seen that still return pretty unfiltered results.
DDG/Bing, Google, Ecosia (Bing), Yahoo, all of the US based search engines have long filtered torrents or websites known for piracy. Places like steamunlocked or steamrips have also been removed.
