I am wanting to user Drupal chat on my site but need a moderations list. I've found the stop word list and user stop word list is enabled in the variables but it doesn't do anything. How do I get this moderation list working. Also what is the behavior if someone uses one of the words on the list?

Hi danielson317,

Which polling method are you using?

I am using the ajax method at the moment. I would eventually like to move to the node.js but that's probably a little ways down the road.

danielson317, stop word list is only available for "iFlyChat" polling method at the moment. Thanks.

In that case may I recommend this code snippet to future users who need chat moderation in the ajax system. It's pretty simple but did the job I needed.
paste into .module file around line 720. after: foreach ($messages as $message) {

      // Grab the words form the stop word list. Just a variable. Edit comma separated list in devel/variable
      $stop_word_list = explode(',', variable_get('drupalchat_stop_word_list', ''));

      // Add regex info to each word. Regex insures only standalone words are blocked. So it will block "test"
      //  but not "attest" if the word "test" is in the stop list.
      $stop_word_list = '/([^\w]|^)' . implode('([^\w]|$)/,/([^\w|^])', $stop_word_list) . '([^\w]|$)/';
      $stop_word_list = explode(',', $stop_word_list);

      // Filter the message to replace stop words with "***"
      $message->message = preg_replace($stop_word_list, '$1***$2', $message->message);
