From the web site: We should all be doing this to have fun. If you get mad or uncontrolled, it is up to you to remove yourself from the fighting. A REF may remove you from the fighting if you do not remove yourself. A REF has the right at any time to ask you to sit out a fight or to remove yourself from the fighting for the rest of the day or the rest of the event. If you are asked to do this, you should cooperate immediately with no complaints or arguing. If you have questions about why you were asked to sit out, you should wait for a while until you are calm and can discuss the situation with the REF rationally.
