The only defense would be to post only a single comment from each username, so that putting multiple points of data together becomes impossible.

Researchers long ago showed how combining two or more sets of data allowed them to effortlessly de anonymize data with computers programs. That has been known for at least 2 decades, back when it was maddening and worrisome but not yet an existential threat to representative democracy and our wellbeing, before malign forces weaponized the unprecedented mass of data now collected, in ways we don’t even know about yet.

Plenty of people with anonymous accounts on social media have been identified also by groups to punish them for comments, typically ones critical of Israel, supposedly identified as such, but it could be just as likely the US government leaked the information to them, or the social media company. But combining all the information you have let slip narrows it down considerably if a computer is used to sort all the information.

time to stop writing on social media

I mean, makes sense to me.

We already reveal a lot of small details in comments. I mentally note every time I’ve done it and I know for sure someone could probably get pretty close to finding at least the general area I live in by just my post history here, let alone any other social media accounts.

Even with all their other flaws, LLMs are fairly good data parsers. Specifically when it comes to taking unstructured data (e.g. “In SF we’ve got…”) and turning it into structured data (e.g. city_of_residence: San Francisco), so it’s not surprising you could use this to just build a dossier of someone’s info and cross-match it with other databases.

Nothing humans couldn’t do before, and nothing intelligence agencies and data brokers don’t already have technology to do, but LLMs will make this a lot more accessible to anyone since it requires less specialization, custom text filters, stuff like that.
