Really hard to comment without seeing it, and seeing what the spider sees. But generally, don't duplicate the content across your own domain. Many examples can be shown to show its OK, but many also exist to show its detrimental.

Easiest way is to minimize the effect and just use "exerpts". So search pages, categories, the main index, only show a small portion of the content, linking to the full story/article/spam.
