I have recently found an X-rayer on my survival server. He has collected many diamonds and other minerals, and I would like to find a way to stop it. He is partnered up with other people, but they don't know that he has X-rayed. If I banned him his partners would not only be mad, but they would still have the diamonds. If then I take the diamonds away from them, they would get even angrier and leave (which I don't want.). If anyone could help I would be very grateful.
(Please Excuse me if this is not the right place to put this, as this is my first time posting a Topic.)
