Hi Shana,
We have an antispam feature on the forums that 'learns' what is considered spam. As part of the protocol there are especially strict spam 'laws' on all new members up to 25 posts. We are notified of any auto-moderated and can then manually approve the post (as well as provide information to our antispam feature that lets it know that your post was *not* spam). We've found this feature to be a great time-saver where previously all threads were reviewed manually and dealt with accordingly; and the rare 'accidental' moderation is easy to fix.
Don't worry, your post has already been approved and the duplicate deleted.
Thanks for posting your question!
