I hate to derail from the main topic, but if I may add something:
In my case at least, speculation is done in jest as opposed to being an obsessive action. Am I dying to know the lyrics to what the little girl is singing?
Of course not. But it's fun to try deciphering her words because it's fun trying to understand what little kids are saying.
I think most speculation is done in good humor as opposed to being a means to spoil a movie/book/ tv show, etc. If this type of behavior is obsessive, I'll personally seek mental help. But if it just annoys someone else, as long as no one gets hurt, there's nothing wrong with it. Guess what: there will be people in life who will annoy or frustrate you for all sorts of things. My method is to just let them be.
D23 will be here soon, and trust me, lots of speculation will be coming with it. Not just here, but all over the internet. Yes, some will be more exuberant than others, but if it makes them happy, who are we to judge?
I don't intend to make enemies here. I'm glad that if something is clearly wrong, people can speak up. On this issue, however, it seems to be a matter of personal distaste as opposed to wrong doing.
Now that I got that off my chest, I want to go back on the topic of Frozen.
For example, are the Frozen dolls from the previous page going to be sold at the D23 Expo as a limited edition of some-sort? I know there will be some Disney Fairytale Designer limited editions, such as
this Snow White.
