My best guess would be that the moderators thought it was spam. While I'm sure you were just trying to create a blog, it could have been seen other wise. Here's what I would do. Have you noticed the spam meters near the bottom of the page? Post a blog entry, then see if the number is any higher. If it is marked as spam, I would just ask one of the moderators about it.
I can't tell you how much this annoys me, but its my fault it happens! Anytime you have forum related problems. Please PM me! This sends an email notification to my computer and/or phone. Then I can use my phone or computer to fix it. Thanks!
