Yes, because I lately have tried to promote my webcomic, I considered to make an anonymous account on twitter and facebook with the remedies you mention: Tor, protonmail etc. But I kind of gave up. I thrive on open decentralised networks like this and Diaspora, where the users decide what they get to see.

But right now Facebook is where it all happens so I have been dependent on people sharing it there anyway. In the end I guess that because of my hatred towards centralised, censored media I stand in the way of myself. But nothing new there :)
