A clan member may not be dismissed

We have a member of the clan infiltrated to harm, and can not eject it simply because it is in fighting position, be a good idea to allow expel someone because we have lost 500 + points clan for a inrregular behavior of this member, if it continue easily lose everything. The infiltrate member is Clan Nightkiller lllMirtalll and injured clan is EliteAlpha, is appreciate to do something about it with the error of the game because they are abused to undermine and destabilize.
