Este artigo da Wired explica que você não consegue encontrar esses serviços porque o O fundador não os quer. Craig chega até a instalar obstáculos técnicos para bloqueá-los especificamente. YMMV se você usar apenas ocasionalmente o script para fins pessoais, mas não se surpreenda se o seu pequeno script invocar a ira de Craig Newmark:
[Craigslist is] hostile to outsiders who want to pull neat technical tricks to improve the site. A few years ago, independent programmer Jeff Atwood created a service that would allow people to search multiple cities at once or even search craigslist globally. Buckmaster arranged some technical interference to kill it off. Another programmer named Ryan Sit created a service called Listpic, which scraped images from craigslist and dumped them into an interface for browsing: You could scan through all the photos from the apartment listings or see pictures of all the dogs up for adoption. Buckmaster banished Listpic, too.
Atualização: adicionou mais contexto da citação para explicar as objeções de Craig a tais serviços:
He had specific objections to both. Listpic ran ads, it put a high burden on craigslist servers, and when he looked at traffic records he noticed that Listpic was being used mainly to enhance enjoyment of the sexy images people posted in their erotic-services ads. Universal search subverts craigslist's mission to enable local, face-to-face transactions; it increases the risk of scams and can be exploited to snatch up bargains, giving technically sophisticated users an advantage over casual browsers. But the very surfeit of these practical objections—many of which probably have technical solutions—hints that the real explanation lies elsewhere, and with a minimum of pressure Buckmaster will state it plainly. It is the same reason that craigslist has never done any of the things that would win approval among Web entrepreneurs, the same reason he has never updated its 1999-era Web design. The reason is that craigslist's users are not asking for such changes.
"I hear this all the time," Buckmaster says. "You guys are so primitive, you are like cavemen. Don't you have any sense of aesthetic? But the people I hear it from are invariably working for firms that want the job of redoing the site. In all the complaints and requests we get from users, this is never one of them. Time spent on the site, the number of people who post—we're the leader. It could be we're doing one or two things right."
