How to limit post indexer by blog ID

I'm trying to use Post Indexer to selectively pull blog posts from only certain blogs. I've decided to manually insert the blog IDs that I want, but it doesn't seem to be working.

This is what I have (starting at line 191):
function post_indexer_post_insert_update($tmp_post_ID){
global $wpdb, $current_site;

if ( ($wpdb->blogid <> 3279) || ($wpdb->blogid <> 2823) || ($wpdb->blogid <> 1312) || ($wpdb->blogid <> 588) || ($wpdb->blogid <> 1080) || ($wpdb->blogid <> 587) || ($wpdb->blogid <> 4452) ) {
     return;
	 }

$tmp_blog_public = get_blog_status( $wpdb->blogid, 'public');
$tmp_blog_archived = get_blog_status( $wpdb->blogid, 'archived');
$tmp_blog_mature = get_blog_status( $wpdb->blogid, 'mature');
$tmp_blog_spam = get_blog_status( $wpdb->blogid, 'spam');
$tmp_blog_deleted = get_blog_status( $wpdb->blogid, 'deleted');

Am I going about it the wrong way? I have successfully been able to exclude blog ID 1 with this:

if ( $wpdb->blogid == 1 ) {
     return;
	 }

But now I want to only include certain blogs.

Any suggestions?
