Just to piggyback on what Brian is saying: The problem is sharing a leaked, internal document gets us (well, Brian) into trouble with Universal because at that point, we're hosting it. There are enough layers of separation present for things like spec maps ... but obviously we've seen in the past people be careless on here with information they've overheard.
We're asking people to use good judgment. Sharing internal documents is an obvious, black and white situation that I think most people understand once they realize it's a rule. There are subtle ways to share information, leaked or not, and then there are hamfisted ways. If you're ever unsure if something is cool to share, reach out. I think we're usually understanding when someone is acting in good faith.
