This sounds almost like someone's grandma spray painting graffiti on her own garage door because no one is taking her concerns about area hoodlums seriously, she'd never come up with anything clever or interesting either.
Why on earth would someone go to the trouble to hack, just to post a piece of garbage about Harper choking on a hashbrown? That makes ZERO sense.
Ever heard of the Vandals? They were a cruel, merciless tribe, back in the days of the Roman Empire, whose entire existence was typified by destruction, hurt, killing and, well, vandalism.
The motives of modern day internet hackers are no different. And just as the Vandals (along with the Huns, who, in modern terms could be likened to liberals) contributed greatly to the demise of the Roman Empire, so will the computer hackers do, to the demise of our world as we know it.
Unless appropriate laws are enacted to prevent them from doing so.
