Interesting question. I'm guessing since you ask about the DCMA you're asking about copyright. Well, we'll vet all our writers, and it should be no problem at all. We'll also delay payment of new writers so that there is no way to do some kind of grab-and-dash.

Its also much much much easier to search for copyrighted material in text than in video or flash content. I can't imagine solving this will be a hard problem.
