What I've been doing is stop saying anything remotely controversial or specifically related to people or society and definitely I don't interact with tweets by socially-aggressive people.

For everything else, I just use throwaways.

And I hate that my name is traceable back to my time in 2007 because it was so cool to use the same unique name everywhere. Nowadays Facebook, Instagram, LINE all are "serious" accounts but all have different IDs and lack my last name.
