No, I do not think that has anything to do with the new craiglist terms of service. The new terms of service just prevents other people from copying the content of the craigslist ad.
So, no the hypothetical woman selling the couch would not be affected by the new terms in any way.
Um...
>> the exclusive right to enforce copyrights against anyone copying, republishing, distributing or preparing derivative works without its consent
Where does it say anything about "other people?" I mean, I doubt Craigslist would sue an actual user for posting on EBay, but they might send EBay a takedown notice for that content.
And if I wrote a piece of software that helped you post the same thing simultaneously on Craigslist and EBay, I bet they'd sue me.
That's not what this is about. CL doesn't care where you post it, or how many times you post it. CL just doesn't want others scraping their website and posting it for you. This is direct action on CL against Padmapper.
Do you really think CL is just going to politely ask?
They can politely ask the poster and see if they posted it elsewhere. If yes, nothing else needs to be done. If no, they are probably going to find out the extent the external website has gone to.
You may be happy to rely on vague "oh, we don't actually enforce that clause" but some of us prefer not to sign away rights for nothing.
