Will a News Feed creating duplicate content on my site get me banned

or penalize me at G, Y and MSN?

[SlimKim]

Here's the skinny:

If I set up a news feed on auto pilot and it creates content ... some say the pages would be considered duplicate content ... the articles would be reproduced / duplicated, but the actual page would be somewhat different.

Would this site be banned / penalized or in good standing?

Thanks for your advice :)
