Yes, scraping is sometimes a big problem. And as soon as one scraping site is dealt with, five others seem to pop up.
I've found the best approach (outside of reports and DMCA take-downs when the violations are extreme) is to strengthen your site's authority and trust. Scrapers usually cannot outrank a strong site that is seen as a trusted authority.
