We pushed a new admin feature tonight that gives site owners more control over who gets to post comments. By default, anyone can leave an unclaimed comment or with a registered Disqus account. You were also able to choose to only allow registered Disqus users to leave a comment.

Now, you can also choose to only allow Disqus users with a verified email address. This is ideal for sites that want the most administrative control over the participants of the discussion.

You can view the option on the Admin/Permissions page (screenshot below).
