ThE ViPeR, this is not a pastebin, where you randomly post your personal snippet and be done with it. When you submit a snippet, be sure it's suitable for the general public. For starters, you should remove this line:> if ($chan == #services-diagnostics) { halt }

Your overall code can further be improved with regex:

on $*:text:$(/\s\Q $+ $me $+ \E\b|(\s\Q $+ $anick $+ \E)\b/iS):#:{
  if ((!$istok(OperServ iServ,$nick,32)) && ($regml(1) = $anick)) { 
    .notice YourNickHere 15,1(12,1Alert15,1)14,1 Your name $&
      was said by 15,1(12,1 $+ $nick $+ 15,1)14,1 on this $&
      server 15,1(12,1 $+ $server $+ 15,1) in this $&
      room 15,1(12,1 $chan $+ 15,1) 14,1 $&
      $time(ddd h:nn.ss TT) 15,1(12,1 $nick $+ 15,1: $1- 12,1)
  }
  else { .notice YourNickHere 15,1(12,1Alert15,1)14,1 Your name was $&
      said by 15,1(12,1 $+ $nick $+ 15,1)14,1 on this $&
      server 15,1(12,1 $+ $server $+ 15,1) in this room $&
      15,1(12,1 $chan $+ 15,1) 14,1 $time(ddd h:nn.ss TT) 15,1(12,1 $nick $+ 15,1: $1- 12,1) 
  }
}

Use !$istok to exclude the server nick, along with an if-then-else condition.
