Organizations like Wikileaks fear one thing: being connected to documents by "soliciting" them. (This is how the U.S. is trying to connect Assange to the U.S. cables). So, these organizations will FIGHT to keep from knowing who you are. They don't want to know. Ever. If they know who you are, then they can be connected to the leak. So, leak away. Your identity is secure. If not, at least leak the documents from a competitor - to make your own business stronger!
