Roommates operated a website designed to match people renting spare rooms with those looking for a place to live. before subscribers could search listings or post housing opportunities on roommate's website, they had to create profiles by answering a series of questions and provide a brief description of themselves and their desired roommate. here are some typical ads: "i am not looking for muslims." "not acceptable: freaks, geeks, prostitutes (male or female), druggies, pet cobras, drama queens, or mortgage brokers." "must be a black gay male! " "we are 3 christian females who love our lord jesus christ we have weekly bible studies and bi-weekly times of fellowship." the fair housing act prohibits discrimination against tenants based on characteristics such as race, sexual orientation, and religion. is roommates or any of the subscribers who wrote the above posts violating the law?
