well, a fanboy is normally regarded as a religious fanatic who is incapable of rational thought. Therefore they should be flamed at every opportunity.

Personally though, I think that a fanboy is more like a patriot. If someone is talking smack about your country, you are likely to defend it. Some people are better at it than others of course, and there are a few PS2 people that I can actually have an intelligent conversation with that more resembles a political debate than a flame war. I have yet to find an Xbox fan that I can talk with though.
But these forums are great. Overall, they are a place where a Nintendo fan can go and talk freely without worrying about someone basically saying that your opinion doesn't count simply because you support one console above another. There are a few trolls of course, but the mods can't really do much about (him) while he isn't technically breaking any rules. I do sometimes wonder why such people bother to stick around though if they hate us so much.

But yes, I really do appreciate the moderation here. They are prompt when called, and they allow us a fair bit of leeway, while upholding the rules at the same time.
