Exercise as punishment wouldn't happen in my home, but I can think of worse things. Maybe the exercise is to get the energy all spent up so that the misbehaviour doesn't continue? Just an idea...my son often acts less appropriate when he needs to burn off some energy.

Public shaming, ie monkey ears is abusive and disgusting in my opinion.

I also don't see how you can spank your child without degrading them?? That seems like an oxymoron to me.
