Face Painting (also referred to as 'MySpin') is internet slang for the practice of sprinkling a social networking profile with embellishments, fantasy, and satire, often with humorous or political intentions. Face painters play with the truthiness of identity by conducting a campaign of misinformation to protect their true identity.

Face Painting is closely related to Google Bombing

The term was coined in 2007 in the wake of the Facebook Beacon backlash and the Soble scandal. Face painters aim to introduce a bit of noise and chaos back into the system, clearing some space for true privacy, and enabling a form of direct political action that does not fall victim to Sunstein's critique of homogeneous, disjoint social sub-networks on the internet.
