For bots to work well in a color room they have to be in Bot Mode.. this can be done for a Metis you want admined by adding a login with botaccess.. for example in WCS its b add to the access.
The other bot needs to have the same.. bot access or type /bot after login (if you dont have a login with bot access added), and then of course it will require you to admin it with a level that can kick.
if your not having luck and you are using WCS for the command to /kick try this %NAME% instead of the rawname variable.
