I wouldn’t think you’d be able to… Unless there’s some authenticated-RSS feed stuff somewhere in the core. The moderation queue is MEANT to be hidden so that users can’t get to it without being logged in and admins.
Now, that being said, an enterprising person could certainly code up a hacked-up version of wp-commentsrss2.php, hidden away somewhere outside of normal access (subfolder, with a blank index.php to keep bots away), and have it specifically output only comments sitting in moderation. Okay, if you wanted to, you could just leave it up in the root and not mess around, if you don’t mind that a bot could crawl and find it.
Otherwise, you take a copy of wp-commentsrss2.php, place it in a subfolder with a blank index.php (well, or die(“go away”) sort of thing…), and then do two modifications:
1. change the require(‘wp-blog-header.php’) to something like require(‘../wp-blog-header.php’)… whatever path it needs to get to the original file.
2. change the occurrances of:
AND $wpdb->comments.comment_approved = ‘1’
… to:
AND $wpdb->comments.comment_approved = ‘0’
… to get stuff in moderation. Or if you want to see moderated AND spam, just flip the original to:
AND $wpdb->comments.comment_approved != ‘1’
