Not sure if it made a difference but I reported all of those last week by name. They made up four parties doing DF dungeons.
Also GM's should have no doubt they are RMT as they had the same surnames as players i've blaclisted for RMT /tell spam. All they need to do is an IP trace on the account that owns the chars doing the spiritbonding and the char that did the /tell spam to see they are connected.
