Interesting question. I assume piracy and smuggling and various other law breaking but I'm not certain. AFAIK the only requirement is a legitimate registration. Again AFAIK the vessels that were directly interfered with (ie by force) all had either falsified registrations or were flagged under countries that aren't currently in any state to actually manage registrations.
Then there's also their participation in what's been termed a shadow fleet, the associated falsification of origin of sanctioned oil, the accessing of ports where they otherwise wouldn't be permitted berth, the lack of insurance in case of environmental damage, etc. As I said previously, much more complex than the mass media portrayal.
Freedom of navigation is a right of countries. Spanish ships have the right to freely traverse the seas next to Greece, etc. So ships have to identify themselves as belonging to a country so that they can benefit from it.
