Bill Trulia is like the newspaper, agents or comapnies place ads on it. Trulia does not control the information. Now withiut an address or link no one can check what you are talking about. If it is a home advertised for sale, simply click on the profile of the listing agent and let them know, they are the ones who placed the listing. If it is a REALTY TRAC AD then you should know Realty Trac does not list or sell homes, they take info from public notices of upcoming foreclsoures and prints it, they want you to click on it and subscribe to their service. It is them you should contact.
