I mean, if you put any image online that hasn't been protected/poisoned in some way, you have to (unfortunately) assume it's in some AI's training data anyway. If the tradeoff for a useful description (! See my other comments about the lack of usefulness) is that an image is also fed into one more training corpus, that would be worth a thought, imho. If the image is protected/poisoned, I'd indeed encourage this whole hypothetical process, just to further sabotage the data.
