3 Duplicate Content Myths
Myth 1: Web Content Theft & Other Internet Copyright/Trademark Violations Are Hard to Pursue
Actually, for written web content, search engines such as Google, MSN and Yahoo! make internet copyright violations easy to resolve than printed content.
It's pretty easy to shut down a content thief of copyright violator and there is no need to waste money for an attorney. You can just file a DMCA Complaint. Usually after filing a complaint, you will get a response within 48-72 hours.
Myth 2: Search Engines Will Penalize Sites with Duplicate Content
Actually, major search engines will not impose a duplicate content penalty to sites with duplicated content. But you WILL be penalized if you have duplicate content in the same site/domain. If a shared content were to be penalized for being a duplicate content, then distributing shared content to other websites would not be a very popular marketing technique.
Myth 3: Content Theft May Destroy Your Site's Value to Visitors
No it wont. Content Theft will not completely destroy your site, it will just erode the links of trusts. The world wide web is just so huge that even if your content does get duplicated to hundreds of other sites, it does not mean that people will find that your site is not original and not worth visiting again.
In conclusion, web based content theft is bad but it will not destroy the value of the web.

Agreed. I have worked on sites with duplicate content, and I don't really notice any affect. A lot of it might get put in supplemental index. I usually remove duplicate content links from dynamic pages from the xml sitemap. Also, I think there is a lot of criteria that gets evaluated before duplicate content because syndication and article republication seem to show up well.
P.s. thanks for the dmca link. i didn't know about that.
