A set of Central rules to regulate digital content featuring a code of ethics and a three-tier grievance redressal framework come into effect in two days without any of the social media giants -- Twitter, Facebook and Instagram -- complying to any of it, government sources said. The rules for news sites and OTT platforms were announced in February and they were given three months to comply. Sources said if the companies fail to follow the rules, their intermediary status can be ended and they may be subject to criminal action.
