Labeling, categorization and context I think are most important.
Like in my archive, under the "people" category there are sub categories for "celebrities", "kooks", "cute kids", "cute women", etc.
But those categories are completely separate from the "sexual" category.
And then separate from that category is the "disgusting and disturbing" category. And then each of those categories has its own sub categories.
Even some of my sub folders have distinctive classifications, like my "cosplay" folder uses mainstream media categorizations, starting with comics, anime, video games, movies... but then sub categorizations are used to delineate more precise details, like Cosplay > Video Games > Metroid then uses labels like "sexual", "zero suit" and names of specific cosplayers.
But like in this thread, I can look at the fuckin file names and I can tell right off the bat that they're all just slopped together into one batch, that there's no coherent naming convention used at all (mostly talking about the images starting with "15").
Given the overall context the OP might want to rethink his folder a bit. Main category, for him, would be something like "Aryan Life" and then use sub categories like "Sexual", "Cute", "Family", "Scenic", "Cosplay", "Red Heads", "Promotional" (stuff with Nazi imagery), etc, etc.
Separations and naming conventions provide clear context regarding the images and ensures you don't wind up sending a bunch of mixed signals. Like you don't expect to see a porn theater or a porn shop right next to a school or a McDonalds... so take that same mentality and apply it to your threads... don't make a thread and put porn and pictures of kids right next to one another... but, then again, when some of your porn images are directly labeled as "amateur"... yeah, you might just as well be wearing a giant sign declaring yourself as a pedophile at that point.
That classification is used, very specifically, for sexual pictures of people who can pass as underage and sometimes it's used by pedophiles to try and mask ACTUAL underage sexual photos as being legal. When most normies or semi-normies see that label... bells and whistles immediately start going off in our heads.
