Graffiti artist Casey Nocket is learning first-hand about the consequences of sharing illegal acts online. She's facing a US-wide national park ban and 200 hours of community service after Modern Hiker and Reddit users identified her as the vandal who painted faces in six parks, including Colorado National Monument and Death Valley. A Reddit hiker drew the earliest known attention to the vandalism, but things really snowballed when MH's Casey Schreiner posted a story detailing Nocket's identity and social networking accounts. That led to a further Reddit discussion, which caught the eye of a National Parks Service investigator... you can guess what happened next.
