Couple things that I would like to add about "Unsportsmanlike Conduct" which seems to be a "Grey Area" that needs to be better defined.
This is a Gaming Community not a Competitive Clan. Some people tend to be serious "try hards" that will do everything that they can to win on every single map. This can be considered Unsportsmanlike Conduct if the person is constantly emptying out our servers.
The People that modify there game files and the games CVAR/DVAR settings via the console (not talking about the settings in the options) to get an unfair advantage is something that really pisses me off. I know for a fact that we have several people that are using ProMod configs and other bullshit to get an unfair advantage. It's my opinion that those people should be permanently removed from our servers. This is Unsportsmanlike Conduct and is against the XI Code of Conduct.
Team Stacking has been a serious problem for a Long Long time. I've even seen a couple Admins do it. There is no way that the same exact people end up on the same exact team on every map, day in and day out. I know of over a dozen regular players, in the evenings, that constantly team stacks. If you can't join a Random team without sitting in spectate until someone joins the other team then, IMO you need to piss off and find somewhere else to play. This can also be considered Unsportsmanlike Conduct.
