that would be no different to the other fixed rooms, the OP's check chat logs and then dish out bans like they do now.
They only have a few permanent rooms on each server, so easier to control. However if they have one for each county (50 odd?) then they have 50 odd extra logs to check and 50 odd rooms without someone to control what is happening at that moment, not sometime later when Admin have had time to check logs.
Then what happens if someone wants to open a similar room on another server? Then we're back to how we are now with freedom of choice as to who opens a room on any server. Otherwise we have more rules to implement and enforce.
I would say it wouldn't be very practical.
