How are they doing it? Like, what repercussions could there be, and how would they prove it was you if you put it on somewhere like 4chan?
I'm seriously curious how they are keeping several 100 people from posting so much as a screen shot. Is there legal action attached to it or something? Most EULA/TOS agreements last an entire 2 minutes in court cases... they are mostly fear machines. NDAs would be similar, or so I would think. The problem comes from overuse and not enforcing them... once someone breaks the NDA, EULA, or TOS and the consequences aren't enforced, that essentially allows everyone to break it, as well as proving that I somehow hurt you by posting a picture of your game.
Similar to copyright laws, and from what little research I did on it, NDAs were "effectively" enforced in the past not because of what was in the NDA, but because the user violated copyright law.
Not encouraging someone to break it, I just don't see how they could keep someone from posting ANYTHING about it ANYWHERE. This is the fucking internet... and every game I've ever seen beta tested, even with the most stringent NDA, had SOME kind of leak. Unless they personally know all the players... "friends and family" beta testing, and trust them.
Thoughts? I've never personally broken an NDA when I was beta testing (WoW, SWG, and a couple others not worth mentioning), and I may just have a massive misunderstanding of how this whole thing works.... I just see them as semi-useless.
