It's alleged to be Chi Chi who said that a model must have two of three:

Huge dick
Great body
Beautiful face

And I think that's true.

But I think you may be onto something with the blurred faces... the idea that it's a little more risque, and the models don't want their faces shown, could be a turn-on for some guys. Perhaps you might try "accidentally" turn the blurring off for a few seconds in some of the videos to create more excitement, I bet the members would really get off on that.
