help merging poll and kill file hacks

in showthread.php i have this

  ////////// poll hack start
$rat_pollcode = "ignoreallpolls";
   if (($post[pollid] <> 0)  && (!isset($ignore[$rat_pollcode]))) { //post has a poll
      $pollmodule = 'pollshow';
      include ('pollmodule.php');
   }	  
   //end of "post has poll"
   else $pollbit = ''; //no poll, nothing returned

//lets get the signature after the poll   
$message=bbcodeparse($post[pagetext],$forumid,$post[allowsmilie]).$pollbit.bbcodeparse($signature,0,$allowsmilies);

  /////end poll hack

and it returns just a thread w/ no poll, which is all fine and good, but i'd like to just not show the thread at all. anything i do in forumdisplay.php doesnt seem to work. any help would be appreciated
