For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. The Securities and Exchange Board of India (Sebi) had carried out a similar exercise in 2017 in a matter related to circulation of messages through WhatsApp. 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. Perpetrators of such fraud use various marketing techniques to attract subscribers on their social media channels.
