Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion. The Security Service of Ukraine said in a tweet that it was able to effectively target Russian convoys near Kyiv because of messages sent to an official Telegram bot account called "STOP Russian War." 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. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted.
