I'm not sure the experiment can be done other than to try interventions on real users of a public social media service as Facebook did in the article I linked. Of course people running those services usually don't have the incentives to test harm reduction strategies and certainly don't want to publicize the results. > the vast majority of users don't create original content That's true now at least most of the time, but I think it's as much because of design and algorithmic decisions by the platforms to emphasize other types of content. Early Facebook in particular was mostly original content shared between people who knew each other. The biggest problem with that was it wasn't very profitable.
