Caution: simple blurring may be reversible, and YouTube admits that their process may not blur all faces. On the other hand, simple face blanking, blue-dotting, or a scramble-suit style superposition (from Philip K. Dick's _A Scanner Darkly_) would be irreversible. Not to mention that YouTube might keep the original source video, whether or not you click "delete original". Maybe.
