I wouldn't waste your time. HighKing will soon be blocked for his edits, if not by anyone else, then surely once Cailil returns. If Murry is simply copying HighKing, then he will be too, or at the very least be put on the same path as HighKing was, with a topic ban first, to see if he truly gets it. It's all about WP:ROPE with editors like this. Given his history though, HighKing is surely all out of rope now. He will most likely be indeffed this time, given the fact Cailil has already had to re-impose the BI topic ban after he went back to the same behaviours that saw it enacted in the first place, and the fact he has clearly ignored his very clear warnings about how not to edit in future.
