Can i hide comments of other people in my facebook channel soc.stream?

if (is_array($this->comments))
{
    echo '<div class="row-fluid">
      <div class="comments preview span12">
      <div class="text-center">Comments</div>';

    foreach ($this->comments['data'] as $comment)
    {
        $date = $this->getTimestamp($comment['created_time'], $dateTimeFormat);

        echo '<div class="row-fluid">
          <div class="span12 comment">
              <div>
                <span class="from text-left"><img src="https://graph.facebook.com/' . $comment['from']['id'] . '/picture" width="25" /> ' . $comment['from']['name'] . '</span>
                <span class="date text-right">' . $date . '</span>
              </div>
              <div class="message">' . $comment['message'] . '</div>
        </div>
        </div>';
    }
    echo '</div>
    </div>';
}
