Why does the 'Spam this blog' link in the Email Notification not work?

Note: This is regarding the Anti-Splog Plugin, for some reason it did not show up in the dropdown menu.

We received an email notification of a new Blog Registration.
We suspect that it was a SPLOG but it was not automatically detected
by your plugin. So we decided to click on the "Spam this blog" link
in the email.

However it did not spam the blog. It only redirected us to Network Dashboard -> Anti-Splog -> Moderation -> Suspected Blogs tab.

The page does not contain any information and when you go to the Sites page, it still showed that the blog was not marked as spam.

Please let us know how to get this working.
