The point isn't really to get it to admit to being an LLM, it's more that I don't want my favourite social media site which I value for the exchanges I have with other people to be overrun by bots. So I feel that pointing it out when it occurs can improve the overall discourse. Maybe I am naive in thinking that it would make a difference, but I'd rather be naive than to cynically resign in defeat. And perhaps in the long-term, open networks like this will lose the war. And at that point I will seek alternatives.
