Banning a user without a fair reason is unacceptable and violates the principle of equal treatment. Every user deserves fair treatment and a chance to explain their actions. Bans such like this not only limit acces to game, but also affects the community's trust in moderation system. Therefore it is important that ban decisions are made transparently and after a through investigation. "bLood" who has ben banned has not broken the rules intentionaly or premeditatedly, his actions were punished immeasurably. It's important to take into account the context and intent of the user's actions. A fair solution and the understanding that anyone can make a mistake unknowingly are crucial to a healthy and trusted online community. As users, we expect a quick and fair response from the owner of the server in the case of an unfair ban. As an administrator, you have many other options to punish a player who unknowingly breaks the (unclear) rules of the game. A permanent ban is definitely too much.
