The king should know that africans will never be a real threat to Evropa. Them having 6 japanese teenagers with a bit of modern knowledge wont change that. Letting the blacks have africa and conquering the rest of the world for Germania would be a good compromise.
This poster was dropped on German soldiers during the 1942-1943 new year to imply everyone was dying and demoralize them (the plausible deniability of the pfp), but the aesthetics can make it easy to misinterpret or appropriate back for pro-Nazi purposes (especially with the "Heil Hitler" in the picture) source
TLDR: without prior context it can look like a nazi poster and i believe the user I am yapping about is reinterpreting said image in said way, but their plausible deniability is basically null with all of the bullshit.
I am assuming you've already reported them, just in case make sure you do separate reports. There was someone who had an edited Azunyan picture filled with nazi symbols removed in hours, but not banned. At this time the mods are not that responsive, but I'd expect some action, even if it's just taking down the profile picture.
