That was the point I think. Just a button with no instructions. Do people blindly click a button for no other reason it is in front of them? Without knowing what it does?
It proves my personal theory of trust. If you create something so large and peaceful(ish) that people instinctively trust it, you can get away with anything. What if the button ran something malicious on your machine? What if it permanently deleted your account and banned that username from ever being used again? What if that button permanently banned you from reddit?
These are things no one considered, because reddit is just a big, friendly Lenny.
