If you start a guild, set guidelines , and invite people in, you are responsible for their actions as it pertains to your guild

If you don't like what they do - remove them from your guild - or expect to be challenged on it.

The alternative is to let them do what they want, and have your guild mean nothing. 

(FYI You constantly try to hold my DT sponsors responsible for my actions - yet another example of your core hypocrisy.  :/)
