Soon we'll have to enter our National ID number every time we go online.
I remember years ago there was an EU project to require every user to identify themselves to access online social networks that could include forums, and theymos said something like that he was not going to pay any attention if a "Bolshevik" EU requirement came for that. In view of what's happened recently, I am not so sure what he would do now if such a requirement came, especially from the USA.
