Spam - Replace node content with a set word.

I wrote a patch that allows you to replace each word in the node content with a defined word (like say "Rat" or "Spam" ;-) See attached. It leaves tags intact, so links, images, styling et cetera will remain in place.

Note that in order for this patch to work (on PHP5.3 anyway) you need to change the function definition of hook_misery_perform:

 /**
  * Implementation of hook_misery_perform().
  */
-function misery_misery_perform($handler, $type, &$params = array()) {
+function misery_misery_perform($handler, $type, $params = array()) {
   switch ($handler) {
     case 'delay':
       $min = variable_get('misery_delay_min', 0);
