Well I had a nice conversation with Brainless GM today. And basically found out that if someone is curing your party to steal the hate of a mob and you don't /tell them to stop there is nothing that the GM's will do about it because it is not considered grief tactics. So basically if you /blist all the CGS and cure their party to get hate to take their mob there is nothing a GM can do since you never recieved a /tell asking you to stop.
Here are the SS of the convo. I edited to take out LS and battle spam.
