Can duplicate content influence your rankings?
Every few months, webmaster forums discuss if search engines
penalize duplicate content.
Duplicate content can happen if web pages publish the same
articles, if different domains point to the same web space

filter because additional domain names that point to the
same web space as the main domain name are usually not
