> step over the moral grey lines of using someone else's data without their consent by claiming my service is better OK, IANAL, but isn't the content of craiglist's post owned by the author of said post, not the Craiglist itself? (sorry haven't read their TOS/TOC). Just like you own your tweets, not the twitter? Otherwise, I could keep posting copyrighted material (like books) and then suing Craiglist for copyright infringement (something Vivendi did to Youtube) since CL would claim responsibility/IP rights. I am sure that CL protect itself from acts like that pushing the blame/responsibility at users (I don't think DMCA would work in each and single case). So one could argue that this is each and every CL author right/responsibility to file copyright infringement claim with whomever harvest CL posts, and CL should, for lack of better words, "mind their own business". In other words, they lack copyrights over the content their users are creating. Sure they can remove the post if it violates TOS, but in the best scenario they could email the author "hey we stumbled upon your CL posting on XYZ website, do you want to file a claim?", but really nothing more than that, right? I know it sound bit weird, but isnt't it what AirBNB and others do: while your local/state law may forbid subletting, AirBNB hands are clean because they are in business of providing a social platform to find and post vacant apartments, not enforce or monitor if their users follow their local renting laws.
