I know squidoo does so I would just like to ask if hubpages do the same.

Thanks!

From their faq

Code:

http://hubpages.com/faq/

7. My hub has been flagged for duplicate content, what does that mean?

Your hub's content has been detected on another site and has incurred a HubScore penalty as a result. You are allowed to post content on HubPages that is also published elsewhere, like your own site or blog - but you cannot place any promotional links on that hub.  Only you can see the alert message at the top of your hub and a pattern of publishing duplicate content will negatively affect your HubScore, as we like to reward authors who publish content unique to our site. It does not matter whether or not you are the original author of this content.

If your Hub is truly unique to HubPages or simply quotes another Web page in a reasonable manner, please request a review of the hub by clicking on "learn more" at the top of the hub. An exception is typically granted only when quoting is done to a minimum, or some commonly-used, public domain, or historical phrases have triggered the duplicate content detector. If your hub has been certified as original by the administrator it will appear at the top of the hub. Once certified as original no HubScore penalty will be applied.

hubpages are the worst of all web2.0 sites

Yep.

Many other sites do as well, so you should spend the time and re-write/write your own content(or outsource it) if you want your pages to stick.
