I have trouble seeing responding as much of a fix, although it depends a bit on the platform. On Reddit, Facebook, and the like, there is a pattern where you have highly upvoted/liked posts, where the top comment is about how the thing is obviously wrong.

Most people just glance at headlines, image, or whatever, and don't read articles or examine comments. Those comments about it being wrong only help inform the subset of people who bother to look at comments.
