Seemed OK for me https://onlyfans.com/jackedvanderzander when I just checked it... I had subbed for a bit, bought some vids. But he was charging quite a bit per video, and his account is ALWAYS on, so it has to be an agency running the page.
Good point, I neglected to think about that result, although one would think that the number of viewers on OnlyFans would go way up if the model could advertise videos for a studio, and more money for the model.
