Imagine this: You're on Reddit, Hacker News, or some forum, posting with a silly username like GamerCat2025 or SecretCoderX. You think you are anonymous, and no one knows you and so you can freely express your thoughts.

Well, a brand-new research paper just blew that idea apart. It's called "Large-scale online deanonymization with LLMs" which is a fancy way of saying "figuring out the real person behind a secret online name".

The researchers include people ETH Zurich and, Anthropic (parent company of Claude), and a research group called MATS and they proved that today's super-powerful AI chatbots can play detective and unmask people way better than ever before.

That's good enough for the courts in most states!

It's actually probably about as good (if not better) than "dental identification through bite marks"
