What to do with duplicate content?
Make sure you notice it and make sure to tell Google about it, because duplicate content is a SEO issue. Searh engines like to show every bit of content only once. To be able to do this they need to decide which of the duplicates is the original. To prevent Google from thinking your content is originaly from the person who ‘syndicated’ it from you, you should make sure that it is easy for Google bot to find your content.
