As a consequence they have to prevent open redirect attacks - <a href="https:&#x2F;&#x2F;www.owasp.org&#x2F;index.php&#x2F;Open_redirect" rel="nofollow">https:&#x2F;&#x2F;www.owasp.org&#x2F;index.php&#x2F;Open_redirect</a> .<p>Yes the same system can be used for censorship - but facebook can do that anyway because you&#x27;re sharing links through a platform they have total control over.<p>The irony (of using a facebook tracking url to promote an anti-facebook site) is beautiful.
