I think people can find this script useful. Menu Channel popup. Works like: When you add user to shitlist, script scans all channels you are in. If you are oped on channel and user is on channel he will get banned. When some gives you operator status script scans channel for shitlisted users automatically. When someone joins script does the same. Hopefully you will like. One of the big minuses is that script uses only Nickname, not host.
