Are you asking why FF is turned off? I can tell you that I performed a new configuration update to all NMRIH servers which by default turns FF off. This came out of a number of complaints of team killers wrecking havoc on the servers with Admins hardly on to deal with it. If we feel FF should be turned on, please make your voice known in this thread!
The first time i played NMRIH i remember there was a group of two guys that would kill everyone at spawn then stay at spawn and spam on the mic. So FF with no admins is absolutly terrible. I think by default it should be off (If FF is still a giant problem on NMRIh) but if an admin is on they should be able to creat a vote to turn it on so that FF is only on when an admin is on to deal with any problems that occure.
