Only an attribution line makes a scraper feel that they can continue to rip off your content, and make money from it.

I have a fairly strong-worded message for mine. I've modified it to include your info. Take it, change it to your needs, and attach it to the posts in your feed:

Seeing a message like that on a scraper's site will let their readers know that the site owner isn't writing their own content, but ripping off off others for profit. A bit embarassing, yes?

Sometimes you have to play hardball. ;)
