Hmm Nice ;)
Why you don't add somthing to don't kick ops and voices people . You can use also this :

on *:text:*:#:{
  if ($opnick == $nick) { halt }
  if ($vnick == $nick) { halt }
  if ($me isop $chan) {
    if ($1 == *www*) { kick $chan $nick has been kicked }
    if ($1 == *http://*) { kick $chan $nick has been kicked }
    if ($1 == *.com) { kick $chan $nick has been kicked }
    if ($1 == *.net) { kick $chan $nick has been kicked }
  }
}

This is very simple Snippet, But I like very much snippet of Jethro_ & Wader ;)
