DuckduckGo's popularity is largely due to the reputation of the search engine, caring for the confidentiality of its users and free from any censorship. Nevertheless, DuckduckGo deleted several large pirate sites from search results, among them The Pirate Bay, 1337x, Fmovies, Nyaa.see and LookMovie.io. Before that, you stated that you would delete from the issuance of "propaganda". I think that you yourself violate your rules and in particular Firefox policies about the free Internet.
P.S. I delete this expansion and will discourage them to enjoy your acquaintances.
