I give my students online quizzes. Online, open book quizzes. Online, open book, open internet quizzes. It's not like I can monitor their sources. They have an inordinate amount of time (3 hours) for a 10 point quiz. Yet, they spell things wrong, and the computer marks them wrong, and then they whine to me that they got it write but they spelled it wrong.
IT WAS OPEN BOOK! CHECK YOUR SPELLING!
So, do I give them the points? I'm think yes on this first quiz, and then specifically stating that it will be no from here on out.
