Thanks, Brajesh,

Appreciate your assistance.
Actually I had a code in place that seemed to work but suddenly stopped.

Here it is:

if ( ! function_exists( 'ucc_wp_insert_post_bp_blogs_record_post' ) ) {
function ucc_wp_insert_post_bp_blogs_record_post() {
	remove_action( 'save_post', 'bp_blogs_record_post', 10, 2 );
	add_action( 'wp_insert_post', 'bp_blogs_record_post', 10, 2 );
} }
add_action( 'init', 'ucc_wp_insert_post_bp_blogs_record_post' );
// Set hide_sitewide to true if the activity should be excluded.
if ( ! function_exists( 'ucc_bp_activity_before_save' ) ) {
function ucc_bp_activity_before_save( &$args ) {
	global $wpdb;
	if ('new_blog_post' == $args->type ) {
		$post_id = $args->secondary_item_id;
		$comment_ids = array();
		$comments = get_comments( "post_id=$post_id" );
		foreach ( $comments as $comment ) {
			$comment_ids[] = $comment->comment_ID;
		}
		if ( in_category( 'community', $post_id ) ) {
			$args->hide_sitewide = false;
			if ( ! empty( $comment_ids ) ) {
				$result = $wpdb->query( $wpdb->prepare( "UPDATE $wpdb->prefix" . "bp_activity SET hide_sitewide = 1 WHERE secondary_item_id IN (" . implode( ',', $comment_ids ) . ")" ) );
			}
		} else {
			$args->hide_sitewide = true;
			if ( ! empty( $comment_ids ) ) {
				$result = $wpdb->query( $wpdb->prepare( "UPDATE $wpdb->prefix" . "bp_activity SET hide_sitewide = 0 WHERE secondary_item_id IN (" . implode( ',', $comment_ids ) . ")" ) );
			}
		}
	}
	
	if ( 'new_blog_comment' == $args->type ) {
		$comment_id = $args->secondary_item_id;
		$comment = get_comment( $comment_id );
		if ( in_category( 'community', $comment->comment_post_ID ) ) {
			$args->hide_sitewide = false;
		} else {
			$args->hide_sitewide = true;
		}
	}
} }
add_action( 'bp_activity_before_save', 'ucc_bp_activity_before_save', 10, 1 );
add_filter( 'bp_after_has_activities_parse_args', 'ray_bp_display_comments_stream' );

Thanks a lot again
