I had this happen to a celeb site I ran back when panda hit. 1. seed your posts to talk about you. 2. Test how long they take to scrap, maybe using trash content, then update with the newer real content. 3. DCMA them, report copyright violations to their hosts and adsense if they are using them.
I got one guy thrown out of google, I got another one's adsense terminated.
It will be a bit of work on your part. Good luck,
Jay
