Craigslist began as a local San Francisco community website but has grown to be one of the most visited English websites globally. It offers classified advertisements across various cities. Though Craigslist operates as a for-profit company with around 25 employees, it generates millions in revenue each year due to its large network of classified listing across major cities. However, it also faces controversies around moderating scam artists and illegal goods/services being advertised on the site.
