If you talk to your child at a very early age and use common sense discipline, by the time they are 7 you usually don't have much of a problem, therefore spanking is not much of an issue. When they are small they will get into things. That's what children do. You just have to let them know why you don't want them to do certain things. Their minds comprehend much more than people give them credit for. A tap on their hand when they are grabbing things they shouldn't, even after they have been told to leave it alone, is a just discipline. Beating a child should never be condoned for any reason.
As a child, I was spanked. I learned to pay attention, therefore, I gave my parents no problems. I can't remember being spanked by the time I reached five years old.
