If the /kick command is causing such strife, yet brings no terminal nor conclusive results in its use, remove it.
Drivers, as authority and role models of Reborn, are expected to use the /redirect command for productive use. I'll go out on a limb and say the Drivers' job description does not entail having fun. If their idea of it is playing hopscotch with users across rooms, they've lost the privilege and it ought to be taken away. As is, they should be permitted the command.
Both Voiced users and Drivers can broadcast the rules currently. There have been no incidents- to my knowledge- of a misuse nor spamming incident with the command. Accordingly, the power to use this ought to stay. Should issue arise, remove it from those causing the trouble.
