Alex, even though some of the promoters (I have seen some of the documentaries listed) state that they deceive the women; it is still unforced. By your logic (unforced=ethical), the porn industry, strictly speaking, is ethical notwithstanding the poor behavior of some recruiters. Given that there are documentaries and other resources that outline the downsides of the industry, there is a degree of self-responsibility that must exist for all of the participants. If the poor behavior of some recruiters makes it entire industry unethical, then the local grocery store is unethical because the cashier will ring up sugary foods without warning you of the health consequences.
