Redirecting when site loaded in iframe, is this possible?

Maybe this is a weird question, and I am not even sure if it is
possible.

Someone is maliciously it seems embedding our website into theirs via
iframe. Is their a way to combat this? To check the url, and redirect
to the correct url?

Our website: http://iapplicate.tv

Their website: http://iapplicate.com

It's not really even hurting us i don't think, but this guy has been
malicious and attempted to sue us in the past, and we'd like to not
give him any help (if you notice, he adds his contact info to the
bottom).

I would be grateful for any help, my skill level is relatively low
when it comes to ruby on rails.
