Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. In the United States, Telegram's lower public profile has helped it mostly avoid high level scrutiny from Congress, but it has not gone unnoticed. 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. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. In 2018, Russia banned Telegram although it reversed the prohibition two years later.
