It states that for certain types of changes/new contact details, there will be a verification email sent, with a link you have to click.
That doesn't involve giving your real identity to anyone.
I am very disappointed in the cultural trend over the last few decades that makes a third-party entity, usually a government, the final arbiter over who someone is. If I want to be a certain name in person, and "logfromblammo" on HN, or another pseudonym somewhere else, I question the motives of anyone who wants to undermine that separation. I think it is a fundamental human right to decide who you are, and the ability to separate your social circles by the identity you use is essential to privacy and free discourse.
Several of the positions I hold as an on-line personality--religion, political views, spectator sport preferences--could be used against me in my job or hometown. An atheist anarchist that doesn't even like football is just one step away from social assassination in my physical location. If I cannot establish a separate and distinct identity to discuss such things in another venue, I cannot be free of the social prejudices of my neighbors, ever.
So I believe your assertion is incorrect. Real name policies promote self-censorship for everyone who is not blessed enough to live in a socially tolerant locale. I am content for logfromblammo to have a separate karma rating than my in-person name, and for it to be a discardable on-line identity. That arrangement can certainly be abused, but making that abuse impossible hurts far more than it helps.
Best regards,
John Doe Jr.
