I’m looking to exclude a single user ID from the main activity feed only. Directly above the main feed, I’m using a shortcode to pull in the latest post from this same single user, thus creating a ‘sticky’ post as this account only posts announcements. However, the code below seems to hide the user’s content across the entire site, so it doesn’t appear in either the shortcode-generate feed or the main feed.

Essentially, is there a way I can specifically target the main buddypress activity feed only with this exclusion? Thanks in advance for any help you can provide.

// hide admin's activities from all activity feeds
function bpfr_hide_admin_activity( $a, $activities ) {

	// ... but allow admin to see his activities!
	if ( is_site_admin() )
	return $activities;

	foreach ( $activities->activities as $key => $activity ) {
		// ID's to exclude, separated by commas. ID 1 is always the superadmin
		if ( $activity->user_id == 784  ) {			

			unset( $activities->activities[$key] );

			$activities->activity_count = $activities->activity_count-1;
			$activities->total_activity_count = $activities->total_activity_count-1;
			$activities->pag_num = $activities->pag_num -1;
		}
	}
	// Renumber the array keys to account for missing items
	$activities_new = array_values( $activities->activities );
	$activities->activities = $activities_new;

	return $activities;

}
add_action( 'bp_has_activities', 'bpfr_hide_admin_activity', 10, 2 );
