Warning! This service is not for spam!
If you have important information but you do not want to reveal your identity to the message recipient, this service is for you. The website, named "Leak", simplifies the anonymity of the messages through a more accessible interface.
This solution allow anonymity. The sender has several options, being identified as a "friend", "colleague", "a family member", "a friend of a friend" or "someone", before entering the text that will be delivered to the recipient. "Leak" will cover you.
It still have problems with Firefox (I couldn't type the email address of the recipient), but it's ok with Chrome, as you can see from the video.
