For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. 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. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. 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.
