The option is now here to send rep bans out to all game servers just as the hub does. Do you think this would be a good addition? This would mean any server active on the hub would have a live ban list based on the hub and rep bans.
Also if you find your server is listed as not streaming in the hub send a pb comand such as pb_sv_ver to the server. If it's still listed as not streaming please contact an PBBans admin to help you find the problem.
