I'm not sure this is any different than any time before.
Before we had the internet, how did you answer questions? You either looked it up in a book, where you then had to make a judgment on whether you trusted the book, or you asked a trusted person, who could give you confidently wrong answers (your parents weren't right every time, were they? :) ).
I think the main difference here is that now anyone can publish, whereas before to make a book exist required the buy in of multiple people (of course, there were always leaflets).
The main difference now is distribution. But you still, as a consumer of information, have to vet your sources.
