A current, though probably now former, WildStar beta tester opted to leak patch notes for the game that is currently in its closed beta phase. As a result, Carbine Studios has opted to share the patch notes with their core and faithful followers. While this won't be an "every time" thing, it's a great boon to all of us this time!
Leaks are a challenge for every game. Here's how it generally works: You identify people who are excited about your game, and map that interest to their machine's ability to play that game. Then you invite them into your house to provide critical feedback on your development team's hard work.
This relationship is governed by a few things, not the least of which is an NDA, or Non-Disclosure Agreement. In our case, It's a legal agreement that is digitally signed by the chosen beta tester. It basically states that by signing the agreement, the tester promises not to share anything they learn about the WildStar beta with the public.
Sure, the NDA is an important document. It is a legal arrangement between us, and our testers. But there's a more important contract we need to discuss: the social contract we have with our testing community. This is an agreement founded on trust and a genuine excitement to invite people that aren't beholden to a Carbine paycheck to join us in our efforts in making the best MMO possible.
