I applied this same strategy, but I must have let my guard down for a moment and somehow Facebook figured out my new email address.

I find this incredibly annoying, and also pretty spooky.

It doesn't have to be you: your old friend has both, and shares their data with Facebook, Snapchat, and/or Whatsapp (all are Facebook) so you have no hope of concealing this.

Here I thought I was being paranoid by practicing complete identity separation opsec. Now it turns out to be barely sufficient for dodging targeted ads. Ugh.

Instagram, not Snapchat, but yes. That's the main part of how they build "shadow profiles" of people without accounts, afaik.

I actually created an email address just for the purpose of creating a facebook account with it. Never shared it with anyone, never really used it for anything other than facebook.

They got me still.

Your friends uploaded their addressbooks, knowingly or unknowingly (e.g. regular use of Instagram, FB Messenger, or WhatsApp, or the FB App would make that seem completely innocent)

So they know "John Smith" whose friends with "Joe User" on Facebook, has an email address for "Joe User" that is different than the one listed for "John Smith"'s account; now they have both. That's part of their business.

Personally, I own a domain. Every retailer, website, etc. I interact with gets their own email address. I have no doubt Facebook knows some of them, and can maybe even connect some of them to my profile -- but it's not certain.

P.S: I don't even use facebook myself.
