were they trying to blur the girls' faces or is that just the really bad quality of the video?
if they were, then they did a really bad job of it
They were blurring it so that if anyone raped and beat them half to death, it wouldn't be their fault because they can't claim they recognized them from the show.
But at the same time, they blurred it so poorly so if anyone wanted to find them, rape and beat them, they can.
