As a result, the pandemic saw many newcomers to Telegram, including prominent anti-vaccine activists who used the app's hands-off approach to share false information on shots, a study from the Institute for Strategic Dialogue shows. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. He said that since his platform does not have the capacity to check all channels, it may restrict some in Russia and Ukraine "for the duration of the conflict," but then reversed course hours later after many users complained that Telegram was an important source of information. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts.
