Kay, I made it to the end and I'm totally convinced. Hans Kristian Graebener is Stonetoss, is Red Panels, is a Nazi (not just a generic American fascist, a Nazi,) does have connections with a bunch of other Nazis, including the Nazis in Patriot Front, does maintain several Nazi sockpuppet accounts online, and is "is an antisemitic, racist, incel, anti-LGBTQ+, Nazi weirdo, who boosts his own content."
They got 'im. You literally cannot be got, more than this thread got that fucker.
