My "real" presence is empty of anything except professional presence. LinkedIn, github etc etc. My "real" presence never engages, never debates and is effectively not there except when it engages with the real world via resumes etc.
My actual presence is scattered across the internet in multiple pseudonymous social networks and eagerly discusses topics I am passionate about.
It occasionally attracts harassment etc, but I dont care cause they cannot reach out into my real life and actually harm me.
