Twitter post from the producers - 

So basically, please keep material that hasn't already been leaked private. If you come across a leak and want to listen to it, or if it's one that's already been around for a while, fine, it's up, it's your personal choice to listen or not. But if you do have information to a leak - or, if by some means you have un-released material - don't spread it around.

Also a note to everyone: Please stop the fanwars over who is or isn't a loyal fan based on their actions, who supports/dislikes the girl in the MV teaser, etc. They are all over facebook, youtube, and twitter, and this infighting among the EXO fanbase is exactly what makes other fans dislike EXO fans/exotics sometimes. Just...stop fighting against each other and freak out quietly. Please. Thanks.
