What about reposts, especially to platforms that don't play the game? The only thing that will stop your naive friend, who thinks your slightly off-color remark about the hot-topic of the week is pure gold, from reposting will be potential threats of legal repercussions if they do (some kind of DMCA amongst friends). Who the hell wants that? We're either asking for the same thing media companies have been seeking for decades, perfect DRM (billions of dollars haven't found that solutions yet), or we're admitting that none of this works unless everyone you share things with, and the people they share your thing with, completely agree with you about who should see the thing you just shared with them, and know how to prevent software from automatically doing it, perfect trust (most can't even keep their contact lists from leaking). I don't see either happening, ever. The goal here is to prevent powerful groups from building a profile so they can target ads/guns at you when they decide they want your money/life whenever they decide they deserve it. The only ways I can think of to do that are post anonymously, hope not to get doxed; or STFU and stop broadcasting your life. You can make laws that might make it unprofitable (most likely just for new-comers, the current players will just pay the fines), but that won't stop the guns.
