Why do some girls take advantage of genuinely nice guys?

This is just an in general question. I hear its because girls can sense "fake kindness" from a mile away but a lot of the dudes I see that are rejected or friendzoned are genuinely nice guys. Please try to go in-depth as possible with this. I understand that this topic is done to death.
