And, somehow, it seems to go against our grain of "be conservative in what you do, be liberal in what you accept from others"[%] policy. I have come across a lot of people who try very hard, but don't always succeed in getting things right, or have a lot of trouble understanding the concept. Penalising them in this rather harsh manner seems somewhat rude to me, and may not be quite the way to coerce people to use the DNS, or to get them to straighten out their end of things.
