Where can I contact Yahoo HQ customer support?

I'm from Indonesia, and, well this is not about feature bug or something like that. It's just here in Indonesia, the comments in Yahoo News is "censored". All comments that support USA dan anti-Osama is deleted indiscriminately. While the comments that's joyous about 9/11 terror attack or supportive of Osama and terror against USA are everywhere. I know it's a small matter for Yahoo, since it's not money-related. But can at least Yahoo (which I assume is an American company) look into this problem, so at least there'll be freedom of speech within Yahoo forum. I'm not asking Yahoo to fight for freedom of speech in Indonesia (well, actually you're free to speak here, but there'll be "consequences". You know what I mean), just freedom of speech in Yahoo Indonesia forum.
