For me it is the same with my chat messages. If someone reads one or two, I don't mind: they aren't very sensitive. But I don't like it if someone can find everything I've ever written.
People over the internet, are little too much over-sensitive. I am not implying 'Privacy' has no value, but we have taken this issue bit too far over the 'internet'.
A prime example of so-called 'anonymity' over the internet is 4chan, you pretty much know what sort site that is.
I am not implying it's an illegal website, but frankly, anonymity mostly leads to creepy, drugs (silkroad), and everything else considered wrong and bad, than something good which is pretty rare. Snowden is an exception, but again, he committed a crime for a good cause. Most people however commit a crime for every possible wrong reasons.
