Wikileaks is a website that has the unique specialty of allowing people to anonymously leak documents over the Internet. Perfect if you want to whistleblow on your government or corporation. It even mentions how to lessen the chances of the data being censored or caught (along with you).
Except for one thing.
The site's running a bit low on funds, and it's going to be September before they get anything large. If you want to donate to them, they'd appreciate it.
