I'm not for two reasons. First, as much as many of us here care about this site, in the universe of the internet it's a niche within a niche. Alexa rankings have CF at #242,063.
Second, it's non-commercial. The images are generally owned by the studios not the actor and the studios care about $s.
What about porn stars? Surely Little Caprice doesn't think people watch her movies for the plot or the depth of character development. I doubt Alice thought she was making documentaries on Roman history. But even for legitimate actors or models, they can't control people's fantasies any more than your hot next door neighbor can (my next door neighbor is a guy, but I can dream can't I?). Weinstein is a problem not because he fantasized about doing those actresses, but because he actually did them or tried to.
My preference though is not to use celebrities in my stories, mostly because I find it more interesting to invent my own characters.
