So if it's not violence...why is it illegal and why should it carry a serious jail sentence?

Everytime you ask the law to regulate something, you open the jar of unintended consequences.

You complain about the government and yet you want to give them more power and responsibility.

Honestly, this revenge porn shit is a moral hysteria that's one of the many tools of spectacle. If this much hysteria were used for something like "Make sure daytime workers receive 30 minutes of sunlight light a day", it'd probably be more effective towards human happiness and productivity.

Oh well.
