bah, it's simple and effective. :P it's quite nice, if someone enters as a "clone" or "bot" it kicks both users on that IP...

Replace the with the room name you don't want clones, or just make it on *:JOIN:#:{ if you want it to work in all the rooms...

on *:JOIN:#<chan>:{
    if ($ialchan($wildsite,#,0) > 1) {
      .cs kick $chan $nick  Bots/Clones are not permitted here.  
      .cs kick $chan $ialchan($wildsite,#,1).nick Bots/Clones are not permitted here.   
    }
  }
