Ketan,
I guess I am confused. What Wendell says makes perfect sense. If you clicked anywhere in that area, you would get a EULA popup. You say you understand that, and I am sure you do. Are you saying that you went to log in, your mouse is 7 mm from the line, and you know that you didn't click it by accident.
But, to answer your question, no, there is nothing new in it, and no, no one did anything wrong. If someone did do something wrong, AC wouldn't force everyone to read the EULA. No one reads a EULA anyway, although with data mining, you kinda have to.
