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.

      Using a VPN does exactly nothing against cookies or device fingerprinting.

          I am using Firefox, and with a shit-load of add-ons that supposedly prevent unwanted cookies and fingerprinting. I use a VPN.

          I was permanently banned from Reddit (for advocating firebombing nazis, as if that’s a bad thing). When I logged in to an alternate account, that account was also permanently banned. Any account I tried to create after that point ended up being banned within a week, regardless of whether or not I was using it. I checked online. Apparently this has become fairly common in the last 2-3 years.

          While you can minimize your digital fingerprint, it’s almost impossible to prevent all digital fingerprinting. The EFF says that I have very strong protection against digital fingerprinting, but I’m still identifiable to a company with sufficient resources to devote to the task.

              There is no such thing as a “good VPN provider”. VPNs were not created for privacy. They exist to allow individual users and groups to network together in enterprise environments

              If you want more security use i2p or tor
