Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts.

For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content.
