It's kind of silly how servers are allowed to ban people without reason, yet have to follow a set of global rules. If that is the case, can't they just ban everyone who complains about their servers not enforcing global rules, and then, with everyone who would report them out of the way, not enforce global rules?
Especially if the first offense isn't a disconnect, in which case, the person who brings the offense to attention of the developers, will get banned, but the server won't be shut down. And if that person is in a clan, then as punishment for tattletaling (the English language has such a terrible word choice for this action), they can ban the entire clan, or friends of the person, or what not. A truly humorous system.
