Some privacy experts say Telegram is not secure enough 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. These entities are reportedly operating nine Telegram channels with more than five million subscribers to whom they were making recommendations on selected listed scrips. Such recommendations induced the investors to deal in the said scrips, thereby creating artificial volume and price rise. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. False news often spreads via public groups, or chats, with potentially fatal effects.
