I feel like since they're still doing this, I feel like they're not ashamed at all, they just want to spread this stuff to kids so they can scar or create another generation of people like them. Or they feel ashamed of it but don't get enough of it to completely stop them, making them addicted to just creating and uploading those kid scaring videos in the internet.
I've somehow wondered of what they're like in person if we ever see them expose their faces, or just find them in the streets, but they would never it's because if they do, there's A chance that the Minecraft community would be crushing them into rubble like crazy, because who knows who are they're identity, some guy, some serial killer, or some old man whose just thought that doing this can make other kids learn about @#%. so they do not wanna enter into A whole fight with A whole Minecraft community, just fleeing off like cowards of nature.
I somehow see A +30 or +40 year old man in my head but it could also be some corrupt teens which are making money out of this, all of these are either.
