Craigslist is an online network providing users with a central database for classified ads and forums from across the globe. Craigslist started in 1995 in Sanfransisco, California and is run by a programmer named Craig Newman. It has sections devoted to jobs, housing, personals, for sale, items wanted, services, community, gigs, resumes and discussion forums.
When you talk about scraping the net, Craigslist comes across as one of the difficult sites to scrape. Developers on most social and commercial sites provide an API, allowing users to scrape data and output it in their preferred format. Craigslist, however, only allows you to post data. This you can do even in bulk. It does not allow you to harvest read-only data. This gives businesses, individuals, and Craigslist the advantages of posting on here. But as Craigslist gains nothing from allowing this same information to be scraped and displayed in non-Craigslist sites, it is structured with the intent of making harvesting from this site an impossible task.
