Expressing contempt for your fans (or potential fans) is an epic losing strategy. I do see negative comments like this on trans Twitter sometimes. Usually they are nobodys in the industry. Maybe they think they can make money by selling their content to the other trans models? I’m going to guess that the more popular a model is, the more likely she is to keep any negative opinions about her fans private.
I’ve never heard of Dominique Rystan and I suspect most fans probably never will.
edit: I just checked her page. She described herself as “destroyer of men” and dominatrix. So she’s made it part of her marketing, for men who want that.
