Craigslist, the online classified advertising site, was sued by the Chicago Lawers' Committee for Civil Rights Under Law, Inc., for hosting users' discriminatory housing postings.

Unlike the decision in Roommates.com, Craigslist was immune from liability for users' discriminatory housing postings because "[n]othing in the service craigslist offers induces anyone to post any particular listing or express a preference for discrimination." The court rejected the claims that Craigslist caused the discriminatory posting just by hosting an interactive web forum. It also rejected the argument that discriminatory housing advertisements were an exception to CDA § 230.
