Does craigslist actually own the copyrights to user generate text and images?

[coliveira]

Of course. From their TOS: "You automatically grant and assign to CL, and you represent and warrant that you have the right to grant and assign to CL, a perpetual, irrevocable, unlimited, fully paid, fully sub-licensable (through multiple tiers), worldwide license to copy, perform, display, distribute, prepare derivative works from (including, without limitation, incorporating into other works) and otherwise use any content that you post."

That just means that the users of Craiglist grant them an unlimited license. The users still own the copyright, though.

Where does Padmapper's license to the listing data originate? When do the posters of listings grant Padmapper a license of any kind?

You don't need a license to link to something.

[runako]

The listing data that is presented and rendered on Padmapper's site isn't linked (e.g. the price & # of bedrooms). That is, I don't have to click a link to go to the original site to view the content.

Padmapper does link to images, but Padmapper would be useless if it didn't also re-publish the content jacked from Craigslist.

[cwp]

Copyright doesn't apply to data. Only the text posted to CL is protected, and Padmapper isn't using that.

Having a broad license is not the same as owning the copyright (especially a non-exclusive license).
