It could also be based on what Grok is being fed from the users... IIRC, there was an early AI bot from Microsoft intended to have the mentality of a young teen, and within a couple days, the bot was a racist slut just from interactions.
It depends on how the bot takes in the information it is interacting with, not necessarily the directions of a single person...
I mean, someone asks, "What's going on with the farmer's in South Africa?" and the bot has seen all the unhinged posts about the topic, and injects that information into the position.
It's not necessarily malice, but yet another example of why I generally don't trust AI platforms and would reject actions based on AI results without external validation.
