Dumn dont kick me from $chan 'Dymn' is just an unneeded typo.

I always thought mirc wouldn't rememer who kicked you out of channel. Upon returning, the revenge kick usually becomes null. Try this one:

on @!*:KICK:#: {
  if ($knick == $me) {
    var -g %x $nick
    join $chan
  }
}
on me:*:JOIN:#: {
  if ($me !isop $chan) { cs op $chan $v1 }
  $iif(%x !ison $chan,mode $chan -o $v1,return)
  kick $chan %x Don't kick me! | unset %x
}
