Among the differences, DDG blocks MFA content mills and junk sites. If you report one they add it quite fast.

Yahoo certainly tries to do that too, although I guess you're getting the union of yahoo/bing's spam-fighting and DDG's spam fighting.

I suspect that of the two, yahoo's has a much bigger impact given the size of the teams involved.

Actually I remove tons of spam from the Yahoo, Bing & other feeds.

[moultano]

What order of magnitude is tons? Not to take away from what you're doing, but historically 90% of new domains are spam.

I'd have to check for exact numbers, but for a large % of searches I'm removing links from those APIs.

Probably because few people report sites.
