>>30514097The originals were jpg downsized. Additionally, the pics had different dimensions (note how the confidential stamp is not the same size).
This points towards pictures taken by a mobile device (unevenly snapped photos), and sharing between a small circle of people (jpg artifacts and overall shit quality).
My guess? Somebody in the localization team shared with close friends/relatives, who shared it with somebody else until eventually someone that frequents 4chan got them.
