I don’t remember how many times did I click a Facebook ad, which took me to the canvas app asking me authorize it immediately. Even before I saw the landing page of the application. But I do remember, how many times did I go through. ZERO! Why would I? I have no idea what is the application about. It usually asks me to provide my email address as well, not explaining why. Do you give your email address to anyone? No, you don’t. And do you know what’s the worst about it?
