The fact that you chose to ban me instead of others that have far more offensive "spam" is the main problem here. I was "spamming" about you, and your inadequacies as an admin. While others constantly spam racist, homophobic, and generally destructive speech.
I wasn't banned because I spammed anything; I was banned because I hurt your feelings.
I did not ban you because you offended me or for anything remotely similar to that. I ban people who don't use their common sense in-game, and who don't listen to admin instructions. After being muted (and deliberately circumventing the mute) you continued in your same course unabated.
The mute was for what you were doing, the ban was for not taking a hint ('go to the forums! This isn't the place for this kind of discussion"). The ban succeeded, somewhat, in that it got you onto here instead of filling up my screen with angry white and green text.
As for other players acting inappropriately I deal with them on a case by case basis. Last night I warned a player because it was reported to me that he was saying racist things in teamchat. The night before that I warned players twice for not "being civil" in chat. Where you're different from these cases is that
you persisted despite repeated warnings to the contrary. I gave you ample opportunity to stop what you were doing and suggested alternative ways to vent about your problems (the forums!).
Though it's true that I don't catch everything this isn't news to anybody. The reason why we have green-text chat is specifically so that significant things can be brought to our attention which we may have missed. It's not for hectoring or any kind of debate.
