The owner of the Moranbong Band video channel describing how views suddenly went down, suspecting Jewtube censors their videos so they don't show up as suggested to watch. Then a few months later views are suddenly coming back up again.
Also, stats show many of the views come from South Korea.
Why would you want to censor the Moranbong girls? I guess because they're wildly popular on jewtube and in Asia. In North Korea their music and videos play everywhere.
