Stop Comments

I have enabled “Users must be registered and logged in to comment.” Registration is disabled and there aren’t any other users except the admin. I wrote every line of the template and it does not contain any commenting functionality. There is not a single plug-in.

I have configured htaccess so, without the password, you can only access /index.php. Accessing /wp-comments-post.php results in 403 Forbidden, whether you have the password or not.

Despite these settings there are still some comments that are making it through. Please advise.
