Privacy is history, almost... but there are still some ways... to build a smoke screen...
We all have our personal ID data (like voice signature, face-image signature etc) in the cloud, and someday someone will be able to match our real and all our "hobby" personalities together in some way or fashion...
But there is still a little hope, we can consciously feed the wrong data into the system if/when the opportunity presents itself. This will contribute in making things difficult for the system to identify us. Its hard to tell how we can do this, but think about it.
