But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. "Someone posing as a Ukrainian citizen just joins the chat and starts spreading misinformation, or gathers data, like the location of shelters," Tsekhanovska said, noting how false messages have urged Ukrainians to turn off their phones at a specific time of night, citing cybersafety. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. In 2018, Russia banned Telegram although it reversed the prohibition two years later. In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback.
