Be careful of how you censor your face. IIRC, there was a wanted suspect who swirl, twirl and whirl his face around with Photoshop and posted the photo on his facebook account. FBI "undo" his edit and he's now incarcerated in a federal or state prison. :bsmilie:
Also there are mathematical algorithms used in digital forensic science which will attempt to add missing bits of data and information intelligently into a pixelated mosaic thus producing several possible facial composites that can be used to identify somebody of interest, I believe some will busted in such way as well. Of course, you'll have nothing to worry about if you are a law-abiding citizen. :bsmilie:
