Вы бы не умничали так сильно. Специально для таких умных, почитайте ФАК на Фейсбуке. Если по английски читаеете, то вот - No, Facebook does not provide a functionality that enables you to track who is viewing your timeline, or parts of your timeline, such as your photos. Third party applications also cannot provide this functionality. Applications that claim to give you this ability will be removed from Facebook for violating policy. You can report applications that provide untrustworthy experiences.
