I remember seeing a YouTube video showing how Daniel Andrews used wubaras/hasmaos to spam one of his tweets with "Good on ya Dan, go get some rest"-type replies. Similar bot armies were also used to agitate for hard Chinese-style lockdowns back when "wash your hands" was the main Corona meme.
A Chinese 'likes factory'. Apparantly this one is used for promoting businesses online
Obviously there are many such government controlled troll factories everywhere on the planet
The wumao will soon become an endangered animal with this type of efficiency
