I read it as this posting is exclusive. I can make a similar posting somewhere else. Sure, I can't copy-pasta, but if CraigsList thinks that because I post on their site that I can't post it on other sites as well I would LOVE to see them try to sue me.
You cant copy pasta your own content. I totally agree though: this will never hold up in court.
If they want to "own" user submitted content, they need a signature. Just putting some terms up will not suffice, unless the site "sell us your exclusive content" with big "make CL own this content" buttons.
