(Snapchat, Facebook, and Instagram are not electronic communication services (ECS) or remote computing services (RCS) for purposes of the Stored Communications Act (18 USC 2510, 2711) which prohibits ECS or RCS disclosure of stored communications even pursuant to subpoena in a criminal case. Those websites do not just transmit messages for their subscribers or store their information for backup purposes but also use the communications and data for the website’s own purposes, such as targeting advertising. Because the services do not fall within the act’s protection, they must comply with criminal subpoenas for subscriber information that a court determines is potentially relevant to the prosecution or defense of a criminal case.)
