Here's a different twist. http://www.facebook.com/apps/application.php?id=213343434487 The Debian(?) user will find no way to block it either, despite instructions on http://www.facebook.com/help/?faq=121070141307903#How-do-I-block-or-unblock-an-app? No. In this case the Debian user won't ever even see a "Block App" link.
