Had never heard of them before now, thanks for the link. Interesting. I dont really want to get entangled with this, i'd just like to have a level playing field. Same site has sniped content of mine in the past as well. More frustrating than anything else.
The thing is, it takes more than "copyrighted content" in order to be actionable. I mean, you can sue anybody for anything in US courts, but it's not apparent from your question that they are taking entire articles, which makes a big difference to the kinds of options you have to deal with it.
If it's entire articles of content for which you hold copyright, you can certainly send a DMCA Takedown notice to their ISP and start the ball rolling that way. Warning: may require lawyer. If they aren't taking whole pieces, then your course of action can get murkier and will definitely become more expensive.
