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. As a result, the pandemic saw many newcomers to Telegram, including prominent anti-vaccine activists who used the app's hands-off approach to share false information on shots, a study from the Institute for Strategic Dialogue shows. False news often spreads via public groups, or chats, with potentially fatal effects. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content.
