By default, any member of a network can comment on the photos, videos, and blog posts you add to that network. You can change this default setting so only your friends can comment on this content, or allow only yourself to comment if you'd like.

You have full control over the comments that other people post on your profile and on your photos, videos, and blog posts. To delete any comment on your profile or your content, click the "x" that appears to the right of the comment.

You can also choose to approve comments on your blog posts and your profile page before they're published. This means that when someone comments on a blog post you've written, it will not appear right away for them. You can review the comment and choose to approve or delete it - before anyone else sees it.

To choose who can comment or to turn on comment moderation for your blog or profile page, click on the "My Settings" link in the right column of the network. Head to the "Privacy" tab to change these settings.
