Sure, if you know the information is wrong or the advice is bad. I have that problem all the time with medics, even official sources. It's why I never take them seriously without thoroughly fact-checking whatever they said.

But what about people who are asking because they don't know? They won't easily be able to distinguish what is right or wrong without triangulating across multiple sources, which most people are not trained to do. What about people in a vulnerable condition? They may not be able to think clearly because of (in the cited case) a disorder, or medication, or they just feel like crap and that makes everything harder. Is there potentially a way to make AI work for sharing information, or is it just too risky?
