Following a series of stalking incidents instigated by a man in Berlin, Masterson – under her previous name of Christianne Carafano – was the petitioner in Carafano v. Metrosplash. com, an online dating service, formerly Matchmaker. com, on which the man had created a fictitious dating profile that contained Masterson's home address, telephone number, four photographs of her, and a description of her that characterized her as licentious. As a result, she received a series of unwanted communications, including obscene telephone calls. When the matter was brought to the attention of Matchmaker. com, that service refused to remove the profile. Masterson then sued Matchmaker. com for defamation, invasion of privacy, misappropriation of the right of publicity and negligence. The United States Court of Appeals for the Ninth Circuit ruled against Masterson, deciding the man who created the profile was responsible for it, and not Matchmaker. com. The court cited Communications Decency Act, which states that "No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider. "
