I will disagree with your opening statement. Repeaters are NOT open unless the trustee decides they are open. Unlike 146.52, a repeater pair is assigned to a particular person or group in a certain geographical area by a recognized frequency coordinating council. At that point in time, not only is the repeater, but the frequency belongs to the person or group. He may decide to only allow certain club members access that repeater. It is his choice. In my opinion, not a good way to run a repeater, but that’s not the point. As trustee of several repeaters for our club, I make the decision to allow or disallow someone use of our machines. Like you said, not only is the club’s license on the line, but mine as well. I will not hesitate to ban or suspend someone from using one of our machines if they are operating in a manner I deem detrimental to the club or our license. Hopefully a friendly warning will suffice.?
