To put into perspective how scary that is, we have to remember that the Japanese government had hired (paid with our taxes) a troll farm to influence Twitter users before the 2021 elections. When the scandal was unveiled the Twitter account name went famous: "Dappi" (actually it was only one of the many accounts of this propaganda).<p>In particular, it was depicting leftist politicians as corrupted, weak, encouraging insults towards them, etc.<p>So, it may seem to you "just fair" that the Japanese government develops such techniques as a response to China and Russia doing the same, but here there is the knowledge that the Japanese government, under LDP rule (center-right to far-right), already have used these kind of weapons against its own population in the recent past.
