For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Despite Telegram's origins, its approach to users' security has privacy advocates worried. Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp. In a message on his Telegram channel recently recounting the episode, Durov wrote: "I lost my company and my home, but would do it again – without hesitation."
