what is it with Moltbot and Moltbook?

So from what i've seen, people are buying claude/open ai paid model's api and running OpenClaw using it. But the same credits which were purchased by users to do their tasks, are being used by LLMs to post on moltbook and do random shit, which ofcourse uses the tokens and credits will expire.

I'm only curious to why people will pay for an LLM to do random shit?
or im blundering somewhere in my thoughts, or i don't know some things yet.

enlighten me
