I agree. It can demonstrate the knee-jerk affect in real time for the reader. Someone who reacts strongly to the title of this thread would have experienced a similar reaction if they had received the SendGrid phish email. Never seen clickbait wording actually be appropriate before.
When I see stories that make me want to click, I read HN comments first, and 8 times in ten that saves me a from a "won't get fooled again" moment.
There's got to be a way to generalize this for anyone who still cares about the difference between real facts and manipulation.
