I just one article that said they were detained in Chile, glad he went to jail.
for the readers who aren’t grown men playing kiddie characters online:
In a 2014 trial against him started in the Norwegian court system for sailing to Antarctica without permission or insurance.[33]After a series of trials and appeals, he was fined and sentenced to 30 days of imprisonment.
And:
The Norwegian adventurer who made an unauthorised trip to Antarctica with a New Zealander on board has been arrested off the coast of Chile.
Jarle Andhoy and his four crew were arrested in waters near the border of Chile and Argentina.
They were escorted to a nearby naval base at Puerto Williams and their sailing permit has been revoked.
Norwegian arrested after Antarctic voyage

but after reading all that, for you to use that as an example of the general public not being allowed to visit Antarctica is crazy.
