@koherecoWatchdog this is a trade-off that I'm very happy to discuss.
I've thought of dropping DDG (and maybe Brave) results entirely. I'm a big fan of Mojeek, but there's a trade-off between privacy purism and relevance of the results that I'm still trying to strike here.
As an example: a search of my name on Mojeek won't return any links to my content on LinkedIn, Medium, or CF-powered websites like Hackernoon, dev.to, IoT4All, BetterProgramming. Nor any links to my books (because they are sold on the likes of Amazon, eBay, ebooks.com or springer.com), nor any links to my music (because, outside of Bandcamp, it's on the likes of Spotify, Tidal etc.), nor any links to my past talks (because they are mostly on YouTube).
Yes, it reports the links to my self-hosted websites and my apps on F-Droid, but those are only a small fraction on the content about me on the web. And the same considerations that apply to searching my name apply to any other search that a user may want to perform. Even the most privacy-aware user wouldn't want to use a search engine that shows to them only a fraction of the web. It should probably be their choice if they want to click on a result hosted on Amazon or Medium. The search engine can ensure that their privacy is protected and that it doesn't collect any private data about users (or that could associate users to queries), but IMHO it shouldn't omit results that may be relevant for what the user actually needs to do.
If users can't find what they're looking for, they'll just fall back on another search engine, which defeats the whole purpose of running an alternative engine. And, if users fall back on another search engine too often, they'll eventually just stop using yours - a point that @thelinuxEXP made quite well in a recent video.
