I have one account here. My real name is on it, for better or for worse. I'm not active on any other social media except to follow some artists on twitter.

I put a lot of care into being self-sovereign over my data, self-hosting what I can and encrypting what I can't. For operational security, I learned a lot from Mitnick's The Art of Invisibility. It may seem less convenient every day, but owning your data when no one else will and staying private when no one else will is worth it.
