Not necessarily. Knowing an image for sure is fake has value, even if you can’t guarantee the reverse is true.

What stops someone from adding a watermark to an actually photographed (carefully framed?) picture to discredit it? There is no certainty either way, just suggestions from someone else about what the truth might be.

No need to theorize, this is already happening.

If you want to discredit an imagine, upload a slightly ai-edited copy of it.
