The Securities and Exchange Board of India (Sebi) had carried out a similar exercise in 2017 in a matter related to circulation of messages through WhatsApp. The regulator took order for the search and seizure operation from Judge Purushottam B Jadhav, Sebi Special Judge / Additional Sessions Judge. "And that set off kind of a battle royale for control of the platform that Durov eventually lost," said Nathalie Maréchal of the Washington advocacy group Ranking Digital Rights. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. In 2018, Russia banned Telegram although it reversed the prohibition two years later.
