The same thing happened to me with SendGrid. I gave them the essay they asked for, just to see whether they'd ask for anything even more ridiculous. Thankfully they didn't, and they unlocked my account so quickly I suspect they didn't even read my intentionally extremely verbose reply. My best guess is that the essay request serves as a CAPTCHA.
