This script will kick and then ban users. For increased effectiveness, their ban protections will be removed and will be re-kicked if they rejoin before being banned.

Instructions:
1) Right Click on User's Name in the Nicklist
2) Goto Control
3) Click on Kick, Ban

menu nicklist {
  Control
  .Kick, Ban {
    mode $chan -ee $1 $address($1,2)
    kick $chan $1
    mode $chan +bb $1 $address($1,2)
    timer 1 2 $iif($1 isin $chan,/kick $chan $nick,/halt)
  }
