CCP Twitter bot: Error 500, this robot accidentally quits, please contact admin (opens in new tab)

Is it really a bot? Or a human that went off the rails? Or an intentional provocation--"we can do whatever we want, mock people and even pretend to be an AI, and nobody can do anything about it?"

This is some high level humor of a bored Chinese teenager. But of course, only works if people fall for it.
