There are private match servers that you can rent with enough admin to change maps. Just hit the links button up the top of this page and there is a Graffiti Taggerz Match Tool and a OTB Server Registration. There are QeHs and Arctic ones but I can't find the link atm. The er33t ones you go to IRC, join #er33t_gaming and type !match and you get given the server, password and ops.
