So lets say I have gave a person host files, and I no longer want them to host... how do I remove there server from my game HUB?
Change your hub password.
But if I have multiple servers on my HUB and I would like to keep a few... That would get rid of them all... How exactly do I remove one and only one without effecting the others?

Store the allowed hosts in a text file and upload that somewhere, then upon world/New read from that file and if the key isn't there delete the world.
You can't AFAIK, you can always send the updated host files to the servers you would like to keep. Albeit you can do what the Darker guy says.
HUB isn't an acronym by the way. They're just hubs.
