Many people exercise poor judgement on Facebook, a site where Freedom of Speech may no longer apply.
Recently, young Facebook users who have posted controversial status messages have ended up in jail. 
Sometimes the messages they typed were actually offensive. Other times they were jokes gone terribly wrong. One teen was even arrested for posting violent rap lyrics.
Most of the time, the Facebook offenders are impulsive. They type before they think, and lately they've had to pay serious consequences.
