Welcome to the Q&A Forum

Hi Rufus, If it's a minor drop, then it might just be temporary. Are you still building links to your site now? Like you, I normally ignore scraper sites. They sometimes give me a lot of good links lol ill gauge it again after 3 months. If it's effect is questionable, then I end up disavowing them right there if it's a really bad looking site. Some scraper sites are really structurally sound and have unique content so I leave those out.
