But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. In 2018, Russia banned Telegram although it reversed the prohibition two years later. Pavel Durov, Telegram's CEO, is known as "the Russian Mark Zuckerberg," for co-founding VKontakte, which is Russian for "in touch," a Facebook imitator that became the country's most popular social networking site. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. In 2014, Pavel Durov fled the country after allies of the Kremlin took control of the social networking site most know just as VK. Russia's intelligence agency had asked Durov to turn over the data of anti-Kremlin protesters. Durov refused to do so.
