It doesn't matter if they know about the techniques. Without good discipline, willpower, and critical thinking skills they will fall victim to the same shyt.
Same reason you know that lady with the phat ass and hourglass shape is using you for your paper and clout but you still fukk with her anyway.

But techniques aren't worth much anyways, I woman knows if she wants to fukk with you or not when she first sees you and your body language. All game or "techniques" is just being able to let her know you're interested and getting her to let you know if she's interested as well without fukkin up her initial interest in you and maximizing your initial value.
