Not every woman who enters that profession is a victim. Quite often, it's the women I hear saying how "empowering" it is for them, and they're usually the ones I hear saying "sex work is work." Many of them sound predatory and brag about the control they have over their clients. I bring this up because there's often a tendency to infantilize women and act as if they have no agency, even though many OF-type models know exactly what they're doing.
Donna Mills is certainly experienced enough to know what she's doing. Teasing and seducing is a great way to lure in a solid customer base, and the fact that she's a celebrity doesn't hurt either. I believe in freedom of speech and expression, so regardless of how I may personally feel about the predatory business model, I believe people have a right to be on these sites if they wish. Banning sexualized material would just create a black market for it anyway.
