I don't think it should be banned outright, but there definitely needs to be more regulation in this field. Child influencers are basically child actors, who have notoriously been taken advantage of by the entertainment industry for ages. While regulations have made things a lot better for child actors, it's still not perfect, but way better than before. There should be pushes for similar protections for child influencers, since they're basically doing the same thing, just on social media instead of in film.
