This is not about restrictions, such lists exist in all countries or at least should exist in all, probably there are some shithoes out there that don't give a damn about this, the only problem is that a list which should have been confidential has been leaked. One good thing is that the article talks only about names, not IDs, so if it's only the name, the whole thing is negligible, I mean, I don't think that in a country with 110 million people there are too many people that don't share both names with each other.
If there's anything or anyone in that list that should be worried about being affected by whatever the hacker plan on doing with the hacked list as their purpose of the hack, then it should be the prominent government officials whose names are said to make the 500 man list.
How is it that such a supposed classified data of information was easily hacked ?! Oh, I forgot it's a centralized server and not inevitable to security risk.
