Picture this: Doctor X claims Y and is selling Z. And there are some reputable websites that question the credentials of Dr X, refute the claims Y or debunk the cures Z. Folks can search the web for Dr X and "quack" a see some warning results.
What if there are currently no such sources for the layman that shed some medical or scientific skepticism specifically upon Dr X and his remedies? For the case I have in mind, I don't think that either the claims Y or the remedies Z are particularly new, I just don't want people to be conned into buying his snake oils – if that's what they are – if there are no results to web searches for Dr X and "quack".
I should add that I suspect that some of his claims are valid but I question his remedies.
