You all seem to have forgotten the unspoken rule:

Always hide your face.

If you're feeling divine, add some color/glow to them, effectively masking your identity, take shots where you're looking away or just stamp a crater over your face and make jokes about it.

Although the above writeup brushes on the topic, it does not mean this. Always hide your true identity. If someone can recognize you on the street by that picture, it isn't mutilated enough.
