But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. Messages are not fully encrypted by default. That means the company could, in theory, access the content of the messages, or be forced to hand over the data at the request of a government. Unlike Silicon Valley giants such as Facebook and Twitter, which run very public anti-disinformation programs, Brooking said: "Telegram is famously lax or absent in its content moderation policy." In 2018, Russia banned Telegram although it reversed the prohibition two years later.
