His identity was revealed the moment he put his actual full name to the paper though :/ I would has sympathy if he actually did use a pseudonym, but assuming this is true then what did he really expect would happen?
I agree that it's harder to have sympathy for him as a result. However, nobody deserves to have their rights violated* because they made a simple mistake. If you forget to lock your house or car, you don't deserve to have it broken into. If you drop your wallet for a moment, you don't deserve to have it stolen.
*If you don't believe in a right to privacy, substitute "be harassed by strangers" or "have their and their family's safety compromised". Even outside a framework of rights, some things remain inappropriate and wrong.
