Seems obvious, but you need a [HIDE-VOTE] option as well so that people can say things in a thread thats hidden to people who haven't already voted.

Approximately this;

	/**
    * Callback function for Parsing [HIDE-VOTE] Tag
    *
    * @param	string	Message text
    *
    * @return	Message (Parsed)
    */

function p_bb_code_hv($message) 
{
  global $vbphrase;
  $message = str_replace('\"', '"', $message);
  // Checking if user can view the message
  if (!$this->_registry->owner) 
  {   
		if ($this->_registry->threadid)
		{
			$creply = $this->_vbulletin->db->query_first("
								SELECT p.pollid, p.votedate 
								FROM " . TABLE_PREFIX . "thread t 
								left join " . TABLE_PREFIX . "pollvote p on t.pollid = p.pollid
								WHERE 
									p.userid = " . $this->_vbulletin->userinfo[userid] . "
									AND t.threadid = " . $this->_registry->threadid . "
									AND userid > 0 LIMIT 1 ");  

			if ($creply['pollid'] > 0 AND $creply['votedate'] > 0)  
				$this->_registry->hvote = true;
		}	
		if ($this->_registry->dohtml) 
		{
			if ($this->_registry->owner OR $this->_registry->hvote) 
			{  $usercansee = true; }	
			$templater = vB_Template::create('vfc_hide_hack_bbcode_vote');
			$templater->register('usercansee', $usercansee);
			$templater->register('postid', $this->_registry->postid);
			$templater->register('message', $message);
			$message = $templater->render();
			return $message;
		} 
		else 
		{
			if ($this->_registry->owner OR $this->_registry->hvote) 
			{  
				return $message;
			}
			else
			{
				return $vbphrase[vfc_hidden_content_reply_vote];;
			}
		}
	}
	return $message;
}

Plus the associated vfc_hide_hack_bbcode_vote template.

And adding this

'HIDE-VOTE' => 'p_bb_code_hv',
to $taglist

etc.

You could go one step more complex and make a hide-vote-option that's only visible to people who selected a specific vote option, but seems unnecessarily complex for most usage.

Otherwise very good mod.
