We ran copyscape last night and we found out that sitekarma duplicated our contents as part of their procedures in there. I would like to ask whether that would hurt our site. Would that end to our site being banned by search engines because they will find that some of our contents have duplicates somewhere in sitekarma? The hompage and some of our pages' contents are duplicated by sitekarma. Any thoughts? Thank you for your help.
Search engines wont ban you for duplicate content but depending on each site's indexed pages and keywords search engines might return sitekarma in the search result page on top of yours, hence reduce your traffic. Check out dmca.com maybe they can help you.
