I get it, but that wasn't the point. There's lots of sites which will have your result and harmful content right next to each other. Reddit is known for being a collection of very unrelated subreddits, but you won't know every site like that. Kagi writes "ensures", but they can't really ensure anything here. They'll have the best guess of the first click being safe and even that is often problematic (what kind of safe?, for what age?).
