Anastasia Vlasova/Getty Images Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. Stocks closed in the red Friday as investors weighed upbeat remarks from Russian President Vladimir Putin about diplomatic discussions with Ukraine against a weaker-than-expected print on U.S. consumer sentiment. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback.
