I was spanked as a child, but not excessively, just when I did things like run out into the road. I don't specifically remember it happening, but my parents tell me it did.
By far the worst spanking I ever had was off a teacher though, even though I was only 6 (so 30 years ago) I remember it very well because it was extremely hard and hurt a lot, it was the only time a teacher had ever hit me before or since, and I had actually not done the thing I was being spanked for.
I did tell my parents, but they didn't believe that a teacher would smack me without being certain I had done what they thought I had.
I am not a parent, so I won't vote.
