This command controls who may set a room to be filtered for profanity. It can be set to ALL, NONE, CHANOP, IRCOP, SA, or ADMIN. If it is set to all then all rooms will be filtered. If it is set to none then no rooms will be filtered. The admin option causes only +L rooms to be filtered and only allows server admins to set a room +L..
/as filter channel admin
This is a good setting if you want censorship to only be set rarely and by people you trust a great deal.
