Attacks can be chained, and this can all be automated. For example, imagine pigbutchering scams... except it's there, similar to some voice-cloning scams, just to get enough data to stylometrically fingerprint you for future reference. You make sure to never comment too much or spicily under your real name, but someone slides into your DMs with a thoughtful, informative, high-quality comment, and you politely strike up an interesting conversation which goes well and you think nothing of it and have forgotten it a week later - and 5 years later you're in jail or fired or have been doxed or been framed. 'Direct methods' can't deliver that kind of capability post hoc, even for actors who do have access to those methods (which is a vanishing percentage of all actors). No one has cheap enough intelligence and skilled labor to do this right now. But they will.
