As a rule, humans do not like to be duped. We like to know which kinds of signals to trust, and which to distrust. Being lulled into trusting a signal only to then have it revealed that the signal was untrustworthy is a shock to the system, unnerving and upsetting. People get angry when they find they have been duped. These reactions are even more heightened when we find we have been duped simply for someone else’s amusement at having done so.
I think that it is interesting to say that human do not like to be duped by others because there are times where those that have duped us are the ones who garner more influence and popularity from duping people. For example, with lonelygirl15, even though people discovered that it was fictional, the channel continue to grow. Another more recent example would be the "Lashgate" tiktok drama where an influencer literally lied to their audience about their sponsorship, yet they are still thriving on tiktok. This goes to show that duping people might lead to more popularity.
