How do you envision that happening? There’s no big database of people’s medical conditions out there that you can use to lookup their name and address, so it’s kind of like an impossible reverse lookup that would need to be done right? Unless you’re talking about a state level actor or something that is tailing someone’s movements around like Jason Bourne and cross referencing it with medical GPT queries, but in that case you’re gonna be compromised anyway in probably far easier ways.
