It's a risk for the Faucet in a Box script.
I can use the form of the faucet and shows on a empty site without advertising. The "form action" is located to the faucet site.

The only problem that I can think of with that is that they would skip over a page with ads and get past the anti-adblock script. Plus, wouldn't they just be stopped by the captcha?
Either way, it seems pretty easy to implement. Just checking against the referrer and returning to the homepage if it was found to be elsewhere should be sufficient.
Something like this maybe:
if($_SERVER['HTTP_REFERER'] != 'http://yoursitewhatever.com'){
header('Location: /');
}
Once the form has submitted (~line 1138 on index.php).
