Mainstream social media track and identify in non-obvious ways such as browser fingerprinting. If you’re on a federated open source social media site then there’s none of that. If you use a VPN (and if you can’t afford one, Proton offer a free tier) or Tor browser to mask your IP and you’re using a non personally identifiable email address that goes a long way towards protecting yourself.

Beyond that, never posting identifying info about yourself such as the place you live, including the State, will protect you even further.

But I do agree that using an E2EE service is the best way to communicate.
