Why Has My Question Been Awaiting Moderation for 6 Days?

I posted a question of how to send requests for reviews to people and it hasn't been posted. The message is "awaiting moderation". I'm wondering how long I have to wait.

I'm a little upset since my rank is low because the review my friend sent isn't showing up. I have to resend it and I have another waiting so I can send him a review request. How long do I and they have to wait for my question to post?
