Answer 1

in your iframe -- post in big letters -- Stop Stealing My Work!

And then it'll be shown on their page, do it for just 30 minutes but repeat as necessary. Keep it random.

And no, I don't know how to do what you are asking beyond embedding a bunch of meta-tag key words and then googling those key words.
