But I still disagree with you not respecting the author's implicit wish. For instance, thanks to the various similar links like the one you just sent, I can pin-point exactly who the person in question is. How can you guarantee the information will not be used against the person? I'm not sure if this is on your ethical framework to consider, but that's where I see the fundamental disagreement.
You could have privately read the text (because you know how to access it), while not posting the text per-se here, and you could even comment something insightful about it. It is more about the anthropological aspect of it, the respect of privacy, not about the technical aspects of the public town-square that the Internet is.
Clearly the author did not know any of these either, nor about what a PhD actually entails. But still, these are mistakes that can be part of someone's life.
