Craigslist is a classified advertisements website that allows users to post items for sale, housing, jobs, and other community notices for specific local areas. It was founded to provide a helpful way for community members to connect without commercial interests. Craigslist has grown to serve over 450 cities worldwide and relies on community moderation to manage posts. While largely successful in facilitating legal transactions and connections, Craigslist also contends with scammers and those misusing the site, requiring moderation of prohibited content and cooperation with authorities.
