I believe that people are talking about blocking balls on their way into the corral from the floor of the arena, not as the human players throw them out. As for detaching your robot. I belive under the current rules that you could as long as both parts stay tethered and there is no danger of entanglement. Not sure about that, relying on shaky memory of past games. As for the legality of blocking the corral's. I would agree that it doesn't sound legal/in the spirit of gracious professionalism, but I don't see anything in the rules saying you can or cannot do it.
