Deceptive advertising has been an issue on Facebook. The company's Beacon program from 2007 invaded users' privacy by monitoring their actions without consent. While laws prohibit false advertising, regulating deceptive ads on social media is challenging. A 2013 case found Facebook's Beacon program violated privacy rights, and the company has since made changes to protect user information and ensure ads are truthful. Continued issues with deceiving users could cause Facebook to lose business.
