If you want to kick a player, you should ban them for about 5 minutes. That will allow enough time for a new player to connect to the server. This is to prevent a player from quickly reconnecting in console to kill his teammates over and over again.
I have thought about adding a feature to disable the limits when an admin is on, but that is basically what notification is for. You should set the FF limit high enough to where, you as admin, would want to remove the player. In this case I would recommend setting it to ban on Team FF limit only, and then use a small Teammate FF limit as your admin notification for potential abuse.
Still if people want it, could add a cvar to disable the Teammate FF limit when an admin is on, so that it can be used as a notification like the above example.
