Actually, if people are willing to be influenced by disinformation on the Internet, I suspect they are not using an "authority" model of information at all. Perhaps all they care about is whether the "information" is useful to whatever causes they believe in, not its source. E.g., an anti-vaxxer reading a post on Facebook that agrees that vaccination is harmful, by this concept would be likely to approve the post (like, share) without wasting time with authorities or fact-checking.
