Hence one of many reasons I don't deal with social media.

Never have, never will.

You may not have social media, but social media most probably have data on you. It has been revealed on the news a few years back that FB's "Like" was intrusive and was able to track you.

I remember reading a few articles on this.

That's why I have dedicated systems based on their usability. One for sensitive account logins, and absolutely no other form of navigation- log In, log out and shutdown. And others that have fingerprinting (browser, sensors, operating system, hardware, location etc) and tracking disabled & anonymized. Of course, I have not distributed any element of personal Information.

Do you use Qubes? I read good things on this OS, and it seems to me like the perfect environment to do what you describe with a single machine.
