I'm not sure, but I am having the same problem.
To elaborate, a user by the name of MUSIC4 or MUSICA is somehow able to join a channel with mod privledges even though no privledges were given to him. He is thus unbannable and uses this to spam some or other links or advertising slogans. Can someone please give an explanation of this?
