Two things:
First, start using the “JS” embed code instead of the “iframe” embed code and enable Referrer Restrictions. This will prevent people from using the JS embed code.
Secondly, come into our live chat and request that iframe protection be added to your account. This is an additional feature which will lock down and prevent use of the old iframe embed code, and comes at no additional cost.
Alternatively, although we recommend doing the two steps above, you can put your content in a javascript code to block people from doing this:
<code><script language=”JavaScript” type=”text/javascript”>if (top.location != location) {top.location.href = document.location.href ; } </script></code>
