Manage Comments link in admin bar not hidden (multisite)

[jaxtheking]

I've installed the plugin and it works perfectly. However I realised that in multisite mode, the Manage Comments link in the toolbar menu for each site is not being hidden (however the linked page is properly redirected).
I am using the following to hide these links, and I thought you may add it to your plugin.

if ( is_multisite() ) {
  foreach ( get_sites() as $site ) {
    switch_to_blog( $site->blog_id );
    $blog_settings = get_option( 'factmaven_dsbl_general' );
    if ( is_array( $blog_settings ) || is_object( $blog_settings ) ) {
      if ( $blog_settings['comments'] == 'disable' ) {
        $wp_admin_bar->remove_node( "blog-{$site->blog_id}-c" );
      }
    }
    restore_current_blog();
  }
}

The code is to be added to the toolbar_menu function (called by the wp_before_admin_bar_render action) in includes/functions-general.php.
I tested it, it works well - not sure if there is a better method.
