In Feist Publications v. Rural Telephone Service Co, a phone directory was ruled to be protected by copyright only if the selection and arrangement of facts was an original creative act (listing numbers alphabetically was not).
I'm aware of a case after Feist where a yellow pages for chinese immigrants was copyrightable because of the creativity involved in selection of the facts and the arrangement into categories. But even then the facts themselves are not copyrightable.
Craigslist's selection is nonexistent, you send it they publish it. And the arrangement of the subset that padmapper is using is solely by geographic location and time. In addition padmapper is not copying the arrangement.
