All of the popular surveillance apps correlate your email address and phone numbers mostly, but if you used 1@gmail.com to sign up for 2@gmail.com google knows and marks it as your altnerate account, it could give them all your 30 rando gmails, you're then linked by phone activations through those emails to everything else, whatsapp, telegram, credit card purchase, etc. the biggest link in the chain is always the phone number though. They also have a big "Alternate Emails" button. Everything fans out from those.

I don't know how deep palantir can build profiles on someone, like digging into comment histories and extrapolating you are x y or z sort of stuff. I'm sure they've learned a lot about people via public irc logs and discord servers. But the only screenshots I've seen have been way more simple than that, basically a facebook UI that gives them buttons for all the apps with the phone # that has been identified as you the user, so it would be your list of social media apps accounts and they just click in and read messages. These screenshots have popped up in court cases recently.

We need to stop using the same phone numbers and rotate them constantly. Ideally back to something like fi that masks your "real" isp account phone number. They need to stop being a 2fa and especially stop being able to identify a person. Carry a dumb 2fa. I've always been on the "dont ask for my phone number to use your service" bandwagon but absolutely now.

And now some banks are doing instant voice recognition. I don't pick up my phone for any number I don't know anymore.
