@arstechnica That's actually old news: Same was reported in 2008 already simply for social graphs. Oh, I see: The article cites it. So this is cold tea served with AI flavor?

@taschenorakel @arstechnica Yes, obviously, LLMs can't magically find who people are so if they're able to unmask pseudonyms, the necessary data is already out there. The main thing here is that it is made a lot more accessible, as people no longer need the know-how, they just need to ask questions.
