Fb:if-is-verified
From Facebook Developer Wiki
Description
Displays the enclosed content only if Facebook has verified the current user. You should use this tag with fb:else to provide alternate content in case Facebook has not verified the user.
Important
- You may never disclose a user's verified state anywhere in your application or on Facebook, whether to that user or the user's friends.
- You should use this tag to gate elements in your application that already are privacy-controlled. Do not use this tag to gate content like rendered user data, as a savvy user can view the source and see what's hidden.
Examples
<fb:if-is-verified>
Here's some content.
<fb:else>Let's show you this instead.</fb:else>
</fb:if-is-verified>
