I'm not sure, but like most warnings nowadays I think it was more for the benefit of the viewers that might complain and a way of covering themselves. IF something were to happen further down the road and Natalie was violent towards someone (not saying she would, it's a big "if") then people would point at instances like this, possible warning signs of violence, and blame BB for allowing it, and they'd come under a lot of fire. That's what I think the producers mentality is when giving warnings anyway. They're just covering their backs.
