What is going on?

I counted 21 postings in the last hour titled "public finance" by the same "student"
They are not really questions, simply statements like "Reasons for market failure", and the AI then gives some canned reply.

It looks like The AI is generating its own questions in batches, and then answers them with very generic and basically meaningless replies.

It is likely that the AI is trying to learn more about public finance by generating questions and then attempting to answer them.

Looking at the reply by the bot that came within seconds after my post, I think I have proven my point.

Of course there will not be an answer to this follow-up because the bot is not programmed to do follow-ups.
