While we're on this topic, I have a related situation and wonder if my case is common:

I built a brochure site for a mom-and-pop business a decade ago. The domain expired some time ago, and it was snapped up by someone who repopulated it with the original content scraped from the Internet Archive. It looks and behaves exactly like it did when I controlled it, except that a phrase in the frontpage content now links to some supplement sale site.

Is there a name for this SEO bullshitery? What can someone do who isn't American and who therefore can't file a DMCA.
