About them thinking they are funny, I think that you were drunk when you posted this.
Since moderation the boards is such sometimes repetitive task, they entertain themselves while doing it by joking with the case, which normally leads people to think they are stupid just because of their behaviour (which is not what they really mean).
They're not. Also I don't think you've been around enough time to talk about such thing. When you get a few more months here you will automatically recognize them for their legendary sarcasm and amusement.
EDIT Not saying that I'm ancient enough to know that with perfection.
