It’s a beautiful Sunday afternoon, and you’re having a nice walk in the park. A stranger approaches you, and he asks if you want a $10 gift card. Already skeptical, he pulls out a lengthy form and states that all you need to do is provide your date of birth, phone number, email, and fill out a survey in order to get the gift card. It’s crazy! Although a free gift card is tempting, he hasn’t done anything to make you trust him with sensitive information and, frankly, it isn’t worth the effort to fill out a lengthy form.
