If anonymity is important, what is the legal basis for defending it?
Against a backdrop of spying revelations and excesses by social media companies especially in regards to facial recognition, there have been recent calls for a "new jurisprudence of anonymity"; see Yale law professor Jed Rubenfeld writing in the Washington Post of 13 Jan 2014. I wonder if there is another way to crack the nut? Because any new jurisprudence is going to take a very long time.
Instead, I suggest we leverage the way most international privacy law and privacy experience -- going back decades -- is technology neutral with regards to the method of collection.
