Just block the domain. At first, you can block manually, but we know Google doesn't like doing things that way. Fortunately, they have a lot of heuristics to find sites like that; usually the content is just copied from another source. And since they scrape the web all the time, they should know which content has appeared first where.

But the issue isn't that they can't; the issue is that they don't want that. Why the sites with copied content exists? To earn money through ads. What earns Google money? Ads!
