That would certainly be an option.
In fact, I believe that all the options you've given are good.
Schools have a role to play, since it's the physical location where there's a lot of social interaction. They know the students and the youth who socialize.
In my opinion, platforms also have a role to play in educating the people who use them to distribute or even create material. I think a lot of platforms allow for the creation of material, such as the Deep Nude app, and things like that. The platforms say that you have to make sure you get the consent of the people concerned when you are creating all this content. However, they know very well that no one is doing it.
I think people need to know what's going on. Users need more protection from these platforms, particularly if they're creating content for the public and they want to try to make money from it.
