This doesn't apply to me because the government in my country didn't ban bitcoin or in other words illegal. I wouldn't use the word violators if bitcoin is banned or illegal in a country but rather use what alastantiger explained which is civil disobedience where a person didn't follow the command or demand of the government.
It is more easy if Bitcoin is Legal Tender or Legal in your country but if it is Alegal or Illegal in your nation, you still can use it too. It's only up to you to be more knowledgeable, experienced in mastering your non custodial wallets, inputs and outputs use as well as other supporting tools for Privacy like Bitcoin Full Node, Tor for your transactions.
Generally you will have to be more carefully if Bitcoin is not yet Legal in your country.
Violators or not it's not for any government to decide. Countries who banned bitcoin are just afraid of it to take over their own currency in delusional way which will not happened to an open market, not corrupt and in dictator type of authority in any country. Instead of buying the statistics of criminals who go to bitcoin to hide, why not open their financial policy just like any big countries who accept bitcoin for what it is. Many people stick their eyes on bitcoin due to investments and its so many features — freedom of their financial use.
Governments can decide your legality status because they have law and law enforcement tools and staffs in hands. How do government use their power to support, serve their citizens or attack against their citizens, it will depend on how that government is structured.
In your life, you mostly can not change how a government is structured and operated so you have to take care of yourself, your fund and privacy first.
