While it might be possible to Insta/FB to do that, I strongly doubt, that they do that or have systems in place to do that. It most likely is not an important use case for them as the user group that does this is way too small. I wonder, if these teens will change to something like, e.g., pixelfed, a distributed image service. That would be a lot more effective in hiding.
