Though I'm not a parent myself, I think I have some information on this topic. I was in from my early childhood years until I was 18, obtaining the rank of Eagle Scout, being a patrol leader (leading 3-8 boys), a senior patrol leader (leading multiple patrols, in my case that was a maximum of about 45 boys) and then being a Junior Assistant Scout Master (I helped the Scout Master, the Adult Leader of the troop, with planning, organization and whatnot), I can say I have my fair share of dealing with troubled youth. Sure, they weren't my children, or even my siblings, but I did have to deal with miscreants, and ne'er do wells.
Usually, when a boy stepped out of line, I would do the first thing that came to mind, when I was younger, this would be something like telling them to stop, then finding an adult. But as I grew in the troop and in life, I realized I could take matters into my own hands. I would tell them they would have to sit something out, like starting a fire (and believe me when I say we all liked starting fires). Depending on the situation, I could be more severe with their punishment. Usually it wasn't necessary, but I can recall having to restrict boys from not attending something they really wanted to go to. I remember having a boy that misbehaved constantly at one summer camp. First, I sent him on latrine duty (cleaning the toilets). That wasn't enough, so I worked with a camp counselor, rearranged his schedule and had him going to places he didn't want to go (he wanted to go to archery and the firing range, instead he ended up in forestry and rowing...) However, even with that, he kept acting poorly. The matter was taken away from me when he was sent home early and some weeks later kick out of the BSA.
The point I make is that passive punishment can be more severe that active punishment. While in scouts, I tried my best to let those who acted poorly to still have fun, but in different ways, hoping to find an avenue where their behavior would be allowed.
I never hit or harmed another scout, but I certainly yelled (once that got me into trouble). But I found, time after time, that most boys learned their lesson by realizing just how dirty bathrooms really are.
