on *:TEXT:!kickuserx:#: {
if (($nick == usera) || ($nick == userb) || ($nick == userc) || ($nick == userd)) { kick $active userX }
}
Another way to do this would be set a user level to users A, B, C, D and then you can do (for example):
on USERX:TEXT:!kickuserx:#:kick # userX
or
on *:TEXT:!kickuserx:#: {
if ($ulevel == USERX) { kick # userX }
}
I believe that's the right identifyer for it
