A facebook employee explained me how tracking works. Its not the email address Meta is concerned about. Its the IP, device identifiers and location. Meta doesnt care about the email at all apart from sending you emails for notification. Even with a fake email they exactly know who you are. Let’s say you visit CNN.com which has facebook tracker. Facebook has the IP and the device identifiers. Now you login with fake email account on Instagram, facebook knows that’s the IP ans the same device hence it “must” be the same person That’s how facebook creates shadow profiles.
Dont use facebook and have a dns filter that kills trackers and adverts such as Control D or pihole
I tried using control d and their dns location changer. Its crap
Really, i have been using the free one that blocks malware, ads, trackers, and social media (spybook, etc) and its been great.
PiHole and RethinkDNS seem to be the best options tbh.

Thats what Control D is for. That way those tracking pixels on other sites are blocked.
