If something is on the internet then it will stay on the internet. That is the princaple I have in my mind while browsing the internet. Especially in an age where everything is archived by someone somewhere. Nothing is inpenetrable.

You can even record your display output with a capture card. If it gets so intense you can try to record your screen with an actual camera in a dark room somewhere. But there will be other problems that are more important before we need to go this far. As I have said before: nothing is inpenetrable.
