So I've actually tried things like this through the API (on opus 4.6, with thinking on and thinking summaries enabled).

For context, LLM APIs are fully stateless, don't include any information about the caller (unless explicitly passed in), and have no access to memory or web search unless explicitly programmed otherwise.

My conclusions are as follows: if the text you pass it looks roughly like it could have been written by some famous internet personality, it will very confidently say that it was written by that personality. I've tried it on some of my HN comments, both from the last few days and from 2023 (before the training cutoff!), most were classified as either Scott Alexander or Patrick mcKenzie (despite the fact that my writing style is very different from those two). When looking at the CoT, it basically tried to match the writing to all internet personalities from this sphere. If it saw something that looked roughly like HN, it went "Is it tptacek... No. Is it jacquesm... No. Is it patio11... yeah, it looks like him!"
