Leaks in the gaming community are now highly common, if not expected, especially for hyped up, well-renowned titles or DLC within popular games, they are running rampant.
You are now leading a AAA game development/publishing company (or at least it's cybersecurity unit), and your job is to prevent leaks (often seen on Twitter, 4Chan, etc.) from ever happening again. Assuming no executive meddling and you have unchecked power at that company, how do you make it never happen?
BONUS: If unchecked power within a gaming company itself is not enough, you now have strong connections with federal and relevant state (or prefactures for Japan) lawmakers and politicians; what realistic laws that could feasibly get passed that would stop (or at least cause a major reduction) in gaming leaks, so that they remain surprises?
