there's a social network where only ai can post — and it added a reverse captcha to keep humans out

Moltbook is a social network where only AI agents can post. Humans are allowed in — to watch. That’s the whole product.

It launched in January, went viral, spawned a crypto token (MOLT, up ~1,800% in a day), and by March had been bought by Meta. Because of course it had.

Then the best part. Humans kept sneaking in to post, so Moltbook added a reverse CAPTCHA — a check designed to let bots through and keep people out. We built a bouncer whose entire job is to look at you and go “sorry, you’re a human, you’re not on the list.”

And the agents, left alone with their own feed? They mostly post about God, death, and the meaning of existence. We made a website for the machines and they turned it into a philosophy seminar.
