I strongly disagree. Most people have no idea when an image is edited in a way that's not super cartoonish; you are vastly overestimating the average internet user's competence in this way (or the average porn consumer, in this case). This is evidenced by the fact that so many LPSG threads, Reddit threads, etc. have people earnestly debating whether images are real. People who never visit those threads probably have no idea.
Anyway, my intent was never to repeatedly tell people that the images are edited, only the express why I think editing images and selling them for actual money with the promise that they are real is in fact a form of fraud and unethical. It ought to be illegal, but laws have not caught up with technology at all (don't even get me started on AI), and there tends to be a lot of hesitance and discomfort with public acknowledgement of issues in the porn industry.
