I feel like good news can distill down to: if there's not enough fact checking in the right domain(s), the editor fucked up. Conspiracy theories, and propaganda obviously fail this test, but do not do so online often enough. Especially not when grifters/propagandists are trying to make money through ads or are state funded by an autocratic government.

Should DDG take into account what is and isn't fact-checked? Absolutely, and if DDG gets better at this, their users will benefit.
