It’s not entirely clear cut.

Douglas P of Death in June (who I meant to reference in my original post) sells (sold?) Algiz Rune pins, and stickers of Totenkophs on rainbow backgrounds (but, he’s openly homosexual) as band merch.

Sol Invictus was formed by Tony Wakefield, who got kicked out of Death in June for being too right wing; and then he subsequently went on to create Above the Ruins for the National Front (interestingly, used to be banned but is back on Spotify), (but now regrets it).

Von Thronsthal use a logo very close to the Schwarze Sonne, and self-published under “Fasci-Nation Recordings”.

Both are on Spotify with no problems.
