I think my siblings were probably worse than me (there was a time when my sister got a pair of compasses and etched my name into the wood of our piano, for example).
There was smacking, but I can’t tell whether it made me better or not, because more than anything else there was the threat of being smacked that hung over you. I know I’m one of the older DiSsers, and thankfully attitudes were definitely changing throughout my childhood - I imagine that for some of the younger people about there wasn’t nearly as much of that threat.
