I know what you mean about spinning it until it is not recognisable, It is worse if the links no longer work as then it is straight plagiarism. I get both varities and do not sweat it as I figure Google will just have to work out which is the original and in the remixes the English is so bad they stick out like a sore thumb! My only concern is the bad back link I may be getting if the link still works as I am sure the sites concerned have negative value only.

I would love it if thousands of people stole my Articles and left all the links intact. - free advertising - Brilliant.

If they left the links, they they're following EZA's rules for posting them. If they posted your article without the links, then they wouldn't be.
So it's not stealing if they're doing it right.

Hmm.. If you have two coins and I take one, am I being charitable or am I thief? It becomes a matter of confounding debate. In either event I feel fortunate. The monkey will take the link they left and not look back.

Hey, that's right. If they didn't change anything and used your links, then that's what you want to happen. It's viral. Now that Google is frowning on duplicate content, your original first indexed content will eventually rank higher.

If they left your links isn't that an approved use of your article?

Hey Art, There really is some divine justice. Not enough though. This war on duplicate content is supposed to help us with that miserable problem. It's really embarrassing when they use your title and name and nothing else and post it on a sleazy site and rank #1 in Google.
