If you knew the rules, and from your location, were asking based on a game you yourself could not play, it means that you are not really facing these problems, and are seemingly asking questions for the sake of asking them. In some eyes, this looks like you are camping the questions, which is generally frowned upon.
Yes, the game might have been available a slight bit earlier in other areas due to time zones and the like, but that doesn't mean that you can just ask questions for the sake of questions - questions should, ideally, come up organically in the course of play, not be asked simply to seed the site with unnecessary content.
If finding locations of items and knowing about game modes is something people want to know about, the questions will get asked. There is no need to prepare ahead of time.
Also, like you said, we have the rules about prerelease questions, and I think that in some eyes, it feels like you are not taking those into account in good faith; instead, it feels like you are bending them slightly in order to ask questions ahead of time. Not saying that is what you did, as I don't have the authority to make judgements on your thought process, but this is how it appeared to the community, and thus, close votes were made.
