Hey Aplive, Where you have

on *:DIALOG:PM:SCLICK:2:{
  /dialog -x PM PM
  /query %pmnick PM Accepted!
}

on *:DIALOG:PM:SCLICK:3:{
  /dialog -x PM PM
  /msg %pmnick I am sorry %pmnick $+ . I have chosen to deny your PM. If you continue to try to PM me I will /ignore you. Have a nice day!
}

You could make it into one on *:DIALOG: event.

on *:DIALOG:PM:SCLICK:2,3:{
  if ($did == 2) {
    /dialog -x PM PM
    /query %pmnick PM Accepted!
  }
  if ($did == 3) {
    /dialog -x PM PM
    /msg %pmnick I am sorry %pmnick $+ . I have chosen to deny your PM. If you continue to try to PM me I will /ignore you. Have a nice day!
    .close -m %pmnick
  }
}
