Just asking a question about prop rules and punishments of sandbox.

Lets say if someone is working on their creation, and they have an unfrozen prop that they are using, and someone shoots that prop constantly away from the owner of it. It's not stated in the rules that shooting props of other players is disallowed, but I am just wondering if this is punishable. I would find this very annoying if I am trying to do something and someone else is preventing me.
