Only if said users happen to commit OPSEC failures themselves. LLMs aren't magic... If someone can figure out who I am or what city I live in just by this username or my comments (with proof), I'll personally send you 500,000 JPY. I'm quite confident that's not going to happen though. The paper referenced in the article does not even explain their exact testing methodology (such as the tools or exact prompts used) because they claim it would be misused for evil. In other words, "trust me bro." Also see the previous discussion here: https://news.ycombinator.com/item?id=47139716
