Forums Scripts & Popups Two questions. ban protection / adverts

Two quick questions for you guys.

1. Has anyone got a little script that will kick users when they advertise? I.e #mychan message. Would be useful!.

2. Is it possible to make a ban protection script?

i.e one op uses it and when someone attempts to ban him, it will auto ban them? Or if thats not possible. a 3rd op has the script and when another op gets banned, it will ban the "banner". Basically to stop channel takeovers.

thanks!
