Healthline is not a trustworthy site- See Wikipedia discussion:
https://en.m.wikipedia.org/wiki/Wikipedia:Reliable_sources/N...?
I think it's reasonably trustworthy for a popular health site, but if I used Kagi I would block Healthline myself. Their Top N lists frequently appear on top of my health related searches when I'm looking for something more scholarly.
I block them, but I block most common health sites. When I'm searching a health condition, I almost always only want Wikipedia. But Wikipedia's search is pretty bad unless you know the exact name of what you're searching for.
Could be because healthline blocks most VPNs and manifest-based ad blockers. Kagi users are basically HN users.
I have it blocked because I had them show up with auto generated (and, obviously, wrong) AI slop results. Anything like that gets an instant block.
IMO I like the fact that they link sources to their claims, which is very rare on the current web. I think of it as a somewhat trustable source of information. Am I wrong?
