But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. "There is a significant risk of insider threat or hacking of Telegram systems that could expose all of these chats to the Russian government," said Eva Galperin with the Electronic Frontier Foundation, which has called for Telegram to improve its privacy practices. The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. 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.
