Replying myself just to add some tidbit regarding the Indo QR Code shenanigans. It seems that my assumption (along with everyone in Facebook group talking about it) was wrong, and that there's no group effort in the whole thing. The Mad guy is the one who did it himself, but then also blamed Kyoon and that Hololive Historian guy Pokka in order to shift the blame or threw them under the bus.
I also noticed that /vt/ already has a thread regarding the QR code stuff (or two, not sure, barely visited the place), and they have this image

The image basically shows that Kyoon was innocent, and when the QR code guy Mad made his "apology" statement that implicates him and holohistorian guy, Kyoon posted the smoking gun in form of a deleted post where he mentioned the exact plan back at 15th august. Mad tried to deflect it ("editan" = "that's an edit"), but realized that he's fucked and thus ditched the server. Kyoon also left, but that's mostly to keep himself out from the folks that went malding and took Mad's blame shifting at face value, and this also confirmed by the discord server members themselves.
Considering that the dude is basically doing vandalism on gooberment property and that there's CCTV and probably eyewitness, he might get the cemen shoes after all. Or at least being humiliated as "that guy who got arrested for vandalizing japanese cartoon images."
