Titles of unpublished nodes (which have comments) appear on the live discussions block

Okay, this solution worked. Looked at the comments.module and saw that function theme_comment_block() had a "WHERE n.status = 1" condition and I added this too to the live_discussions module. In line 83 just change

 // create the SQL
      $query = "SELECT c.nid, n.title, COUNT(c.nid) AS comment_count, MAX(c.timestamp) AS the_time FROM {comments} c ".
               "LEFT JOIN {node} n ON n.nid = c.nid WHERE c.status = 0 ".$select_blog." GROUP BY c.nid ORDER BY the_time DESC ".
               "LIMIT ".$commented_limit;
