Profanity filtering in AjaxChat

AjaxChat provide a Client side profanity filter but this is not cool because:

a) Big arrays of profanities on your client is going to kill javascript
b) You are going to be passing your users an array of profanities.

Fix? Do it server side. giggidy. Jump into /ajaxchat/lib/class/AJAXChat.php

Just above the insertCustomMessage function add

 function filterMessageText($text){
    $prof = array("badword1","badword2"); // extend this with your bad words..
    $replace = array();
    foreach ($prof as $word){
       $replace[] = str_repeat('*', strlen($word));
    }
    return str_ireplace($prof, $replace, $text);
  }

Go to line 1498 and add:

// Copies the original text to a value we can store in a separate table if we want to.
   $original_text = $text;
// Pass the text through the filter.
          $text = $this->filterMessageText($text);
