False news often spreads via public groups, or chats, with potentially fatal effects. 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. Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies.
