I'm not arguing against anonymity, i am arguing that there is a ethical difference between releasing information about that there's a difference between what a politician says publicly and what the politician really thinks, and the same situation with a private citizen.
A politician wants to change the laws and circumstances for our lives, and he/she gets a mandate to do that by convincing the voters that they have aligned interests.
In this case though it was mostly normal citizens who weren't politicians and they used illegal methods in order to gain personal information about them.
