When you create a new blog, comments are disabled by default. The comment settings have three options:
Comments are disabled: Visitors to your blog can't leave comments on posts.
Comments are allowed, pending moderation: Visitors to your blog can leave comments, but you will need to review the comments before they will appear on your blog.
Comments are allowed, and are automatically published: Visitors to your blog can leave comments and they will appear on your blog without your review.
