U can kick people regardless of there name.. Just use that console... bring it up by pressing the ~ key.. and type status
then u will have a list of players in the server... from there look for the player causing the problems.. and before his name you should see a number, like 1,2,3,4,5 ect.. so then you type in the console type the following. clientkick 1,2,3,4,5 ect... what ever the number of the person is,.. that easy there kicked...

~
status (find the player)
clientkick # of the player,,, dont forget the space after clientkick

Workz for me,, hope it does for u
