False news often spreads via public groups, or chats, with potentially fatal effects. "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. 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. In December 2021, Sebi officials had conducted a search and seizure operation at the premises of certain persons carrying out similar manipulative activities through Telegram channels.
