Private posts are visible only to administrators and editors, but I have found that they are displayed publicly in RSS feeds.
How can I remove them from there?

I have this code but it doesn't work:

```
function removeRssPrivatePost($content)
{
  global $post;
  if ($post->post_status == 'private') {
    return;
  }

  return $content;
}
add_filter('the_excerpt_rss', 'removeRssPrivatePost');
add_filter('the_content_feed', 'removeRssPrivatePost');

```
