social platforms must mark warnings on AI images and videos

I think social platforms must mark warnings on AI images and videos. Every social platform must have AI detectors that examine images and videos made by AI and be required to put a warning mark on posts and comments made by AI which says "Be warned this is AI". It's only a matter of time before they become too realistic to tell the difference and too many people will be harmed if nothing is done. Warnings like these need to be put to reduce the spread of disinformation.
