People seriously believe being advertised at is "just as much a negative" as the stigma from being a porn actress? I have no appreciation for the advertising industry, but this is hard for me to believe.
Of course the men choose to contribute but the incentive structure is for the women to foster a sense of intimacy or connection so they can exploit it for cash. It's a voluntary association, but it doesn't seem like a morally neutral or harmless association to me.
This is not to say that the harm men face from exploitation is greater than the harm that women face - or that women don't also face this phenomenon, but just that it is also a harmful byproduct of the service.
