Wordpress also has a widget that prevents people from highlighting and copying content as well.

If someone infringes on your copyright, the first step is to e-mail them a cease and desist request. Once sent, open it in your sent folder and print it out (print to pdf is probably ok). Keep a record of any contacts you attempt and replies you receive.

people are going to copy..it happens, them copying doesnt make your Rank go down. You still have more backlinks than them so you wont lose anything. Commensalism, he copies and you arent harmed
