A user, let's call him Stanley, who has a history of being disruptive posted some mildly off-topic messages in the Prothalamos. The Curator, in an excess of zeal, deleted the messages but refused to provide a proper reasoning. Stanley asked the Curator why his messages were deleted but the Curator refused to answer any PMs by Stanley and instead asked the Admins to ban Stanley from posting in the Prothalamos.
The admins decided this was abuse of power and tried to remove the Curator from office but rolled a 1 on the dice check and it resulted in critical failure. The Curator responded by removing all Admins from the Citizen user-group, not knowing that Admins can post anywhere anyway, and started a VonC against all site-admins.
It's impossible to VonC an admin, only GED has the authority to remove an Admin from office, not even other admins are allowed to remove other admins.
