Show HN: Can you tell a real tweet of a certain user from an AI one? (socialsimbench.com)

Just a small game I coded up for research.

After some limited tests, people tend to pick the AI-written post as the real one more than 55% of the time, almost 60%.

So apparently LLMs kinda pass the Turing test when it comes to social media posts and not even general social media posts, but posts of a specific user!?
