I entered into a free contest in Canada but I did not win. But when I searched for my own email address, I found a public Google docs that contains the address, date of birth, email, name, and phone number of around 79,000 entrants. Clearly this is wrong and unreasonable - no organization should be negligent like this.
Thus what can I do? How do I tell all these other people of this breach of privacy?
I have taken a screenshot of this Google doc.
