I think it would be easer to list the nicks who you don't want to have ops in the user list then to edit your script for each nick. Now if someone is oping a unwanted nick as an op. Just turn on OPGUARD Chanserv will deop them.

on *:op:#YOURCHAN: {
if $ulist($address($opnick,5)) {
mode # -o $opnick
}
}
