I think when I got that junk a few years back there was something about fines or possibly jail time, but I might be mistaken.
This is likely the fear-mongering other slaves tell each other to stay in line. I used to believe it myself. Not sure I do anymore.
When researching this I remember reading the "if prosecuted and convicted you could face up to 5 years in prison or a fine $250,000". I'm pretty sure the only time they might prosecute someone is if the person talks to a newspaper or something and says they're not registering in civil disobedience.
