I use a number of different search engines for different purposes. Yandex offers sites duckduckgo doesn't. Duckduckgo offers sites Google doesn't Google is good overall and at image searching.

You seem like someone who has used a number of search engines. How does it treat sites Google blacklists like nsfw sites or porn sites or torrent sites? Does typing in movie/book/game torrent bring up listings the way Google previously did? How does it treat older non-mobile friendly sites? Is the image search comparable to Google?
