Business-focused social media platform LinkedIn has been slapped with three digital privacy class actions contending that it illegally intercepted users' sensitive health care information to use in targeted advertising.

All three cases, filed by Bursor & Fisher in U.S. District Court for the Northern District of California and the Santa Clara County Superior Court, asserted wiretapping claims under the California Invasion of Privacy Act. The claims were brought on behalf of class members who made appointments on the websites of health care companies Spring Fertility, a fertility clinic; online psychotherapy platform Therapymatch Inc., doing business as Headway; and accessible urgent care provider Village Practice Management Co., doing business as CityMD.
