Also there's a lot of russian kids into it too for some reason, like I keep encountering russians in discussions about the show frequently enough to mention.
I have noticed this phenomenon too. The Hearts of Iron IV modding community has a sizeable amount of Russians, and the amount of them having MD profile pictures or posting MD-related media on Discord (I only use it for getting my mod-related news) is noticeable. In a mod with 500,000 subscribers on the Steam Workshop, the Russian devs have straight-up put MD references as easter egg into the game.


I also believe it's not just Russians, but people all over from the former Soviet Union. I remember seeing an MD fanart that had text that was written in Karakalpak, a minority language in Uzbekistan with less than a million speakers (I am autistic enough to recognize obscure Turkic languages). It's a shame I didn't save it, not because it was that good, but because of the novelty of having text written in such a rare non-Western language.
I even stumbled upon a Georgian (ქართველი) man making an MD-themed HOI4 mod (and it already has 2,500 subscribers).
And funnily enough, it's not the only MD-themed mod that is being worked on.
Other GLITCH-related stuff is pretty much nonexistent in the HOI4 community. At least you don't have to worry about underage TADC fans learning about Oskar Dirlewanger.
On the other hand, I found a teaser for a Vivziepop-led Central America.
now I'm wondering if there's lucha of them, like Homero y Lisa Simpson, or Shrek y Donkey or any of the thirty nine sets of Tortugas Ninjas
It's always either Latin Americans (and never Iberians) or Southeast Asians who are doing stuff like this. They are like parasites to Western culture; they never innovate, just take and ruin our stuff.
At least South Asian countries like India and Pakistan can produce enough media for themselves that you don't see them that often compared to Latinxs and SEAmonkeys despite GLITCH shows having both Hindi and Urdu dubs (yes, you can watch Pomni speaking like a Pajeeta in two different ways).
I swear the only reason TADC manages to get to so many really young children is literally just because it looks kiddy enough on the outside that parents glance at it on their ipad, go "oh how sweet" then assume it's like cocomellon or something without bothering to check further.
Theoretically, what could one do to prevent cartoons like TADC or HH/HB from becoming popular with children? There must be one to filter them without changing the quirkiness and the art style. Maybe one could put in some jargon that only adults can understand; that could work, I believe.
