If we can agree that sexual strategy is amoral, are there any ethical or moral problems to out-manoeuvring a guy who declares himself a red pill man?

It's not something I am planning, just something I am curious about. I can't see how there could be a moral objection to someone deciding to use a declared red piller for dinners, dates, etc, without having any intention of sleeping with him, ever, nor allowing him access to her higher social circles.

It's obviously immoral with a normal guy or anyone sincere in their intentions, but I kind of like the idea that there is a group of guys who have implicitly agreed to let themselves be the subject of amoral strategy, if I understand correctly.
