I might be using a dead person's account at several grocery stores. I just never updated the phone number I used, who knows what bucket my purchasing data goes into. But I hope it causes some inconsistency somewhere.
I have opened several cards over time. I assume they also correlate with the payment card ID (and maybe facial recognition these days).
I also hope my use of random names and emails for captive portal logins is annoying someone somewhere. Tip for anyone looking: its rare you need to give a real email, because if you need to get on the WiFi, they can't really assume you can receive an email until you do.
At least, when I do see ads, they seem very untargeted generic to me so hopefully the algorithms are struggling to lock on!
