Server config suggestion

[Karma]

If it feasible to create a server config parameter (or even an in-game command) that when set to true/false will essentially block non-premium registrees from joining your server?

I'd like to have something like this for my server as it will make it exponentially easier to deal with griefers.

Thanks.
