This is only a civil action and a civil penalty. I've read that the vast majority of these "small" civil penalties are never paid and never collected upon by the FCC. Most of the disturbed, insane hams that do these things and act these ways simply continue unabated. I had one guy stalking me for a while on the airwaves. He would find my QSOs and do some crazy shit. This went on for two weeks until he got bored and moved on to torture someone else. I looked him up. He already had three judgements against him by the FCC. AFIAK, he never paid a dime, and probably continues unabated to this day.
If you are a major violator and subject to 6 or 7 figure penalties, the FCC will come after you for their money. However such judgements are generally reserved for infractions of the lucrative and competitive common carrier and broadcast markets, not LMR or amateur stuff.
