I would just like to say that I totally agree with, and support, Kenneth's decision but that I have something furthur to add to the discussion which I feel is rather important.
yeah i spoke to masternoob, i have full power over who gets banned from my lobby...
Whilst this is true, we also expect the lobby leaders on our site to be courteous and considerate to the people in their lobbies. Just because it is your server it does not mean you can insist that people do something stupid and arbitary because the right to control who is on your server and the right to use your server as a host for a TF2C lobby are not the same thing. TF2C staff are letting you use their servers to arrange lobbies on yours for free and the only thing we ask in return is that lobby leaders do not abuse such privaledges and in my view this is an abuse of your privaledge whether or not you think it's serious. This is not your call to make as you are not a TF2C admin nor do you have any claim to the property of TF2C.
I agree that your actions are not the worst behaviour of a lobby leader I've seen on the site by a long way but that dosen't mean that I approve of your actions and it also dosen't mean that you are not breaching the rules.
Remember, your server is your property and you are right that you retain full control over the server. However TF2C do not have to give you the option to create lobbies on our site with your server and herein lies the fundamental difference between what Masternoob said and the context you are using it in.
With that out of the way, I would also like to remind all users, regardless of rank, to keep their tone civial in all areas of the forum, regardless of the circumstances.
If you would like to check anything I have said then you can find a copy of our rules here.
