I had no luck trying to get these three copied hubs removed over the past year by contacting the site owners. One was a blog owned by a teacher, one was on a Russian site, and the third was some second-rate metal detecting business. In the end I went directly to the hosting companies. Each one responded immediately. Two of the articles were removed on the same day and the third was removed today. Yay.
Forget trying to appeal to the owner's better nature, use Whois and go directly to the host.
Wonderful. I just usually report to Google. That said, I have been lucky with companies and they have taken them down. The one owner who didn't (and it took me months) eventually suffered the consequences of a google take down.
I also had to do a takedown. It turned out that someone had inserted malware on their website and was posting illegally. They thanked me for alerting them to this. I believe them because my essay was inserted right in the middle of something else and was totally irrelevant to the purpose of the website.
I'm happy you finally got rid of the crazy things. I think blocking the one may have ended the spot. If it's still there, I'll do the other. It's almost like someone was jealous. They could've written their own spot. Funny how they seem to think someone just trying to start out is somehow gonna connect them to someone important. I guess if that was the thinking I should be flattered. It's just weird'
