These rules require that the intermediaries, including national and international social networking sites and matrimonial sites, shall observe due diligence while discharging their duties and shall inform the users of computer resources not to host, display, upload, modify, publish, transmit, update or share any information that is harmful, objectionable, affect minors and unlawful in any way, the minister said.
The government has issued the advisory Aug 17, 2012 to all intermediaries.
