SEE EDIT!

They’re literally called “National Socialist Party” (though it seems they are more national “Bolsheviks”). It’s not like this is an important party either, searching for the mentioned person yields zero useful information.

btw. the Swedish person seems to be ok, they’re affiliated with the Korean Friends Association (KFA)

edit: It seems I have mistaken this party for another party of the same name. Even though the name is misleading and stupid and naive, they are pretty based. By which I mean they support AES countries and don’t support nazism or fascism. Still, the name is stupid.
