Duplicate content is probably the biggest myth ever created by seo rainmakers. Feeds and/or gallery submissions (and other types of submissions) you've probably gotten sign ups never would have been indexed or really have any use whatsoever if it were a legit concern.

That being said (and what I think is being alluded to), you still should be reworking content for focus on making sales and or your keyword search targets.

I have never been penalized for duplicate content (or any other myths created by seo rainmakers). Of course more relevant sites with fresher content have pushed mine back until I work mine back into position again.
