    desc 'self-destruct', 'Erase the server from the federation'
    long_desc <<~LONG_DESC
      Erase the server from the federation by broadcasting account delete
      activities to all known other servers. This allows a "clean exit" from
      running a Mastodon server, as it leaves next to no cache behind on
      other servers.

      This command is always interactive and requires confirmation twice.

      No local data is actually deleted, because emptying the
      database or removing files is much faster through other, external
      means, such as e.g. deleting the entire VPS. However, because other
      servers will delete data about local users, but no local data will be
      updated (such as e.g. followers), there will be a state mismatch
      that will lead to glitches and issues if you then continue to run and use
      the server.

      So either you know exactly what you are doing, or you are starting
      from a blank slate afterwards by manually clearing out all the local
      data!
