RE: Who is guilty of fake news? Influencers or their audience?

The truth is, for some people, the proof of quality they need is the face of a celebrity or influencer. Once someone popular endorses it, they would be happy to follow it to the letter. Even if a footballer decided to endorse whitening cream, even though that is clearly not a field that he has any authority in, there are those who will still buy it because of the footballer. That's the kind of power these guys have on their audience.
