There was a discussion about this yesterday in #announcements channel on slack, for anyone interested.

The auto-invites are disabled due to the overwhelming spam couple of months back. The OP will be updated with the new invite page, when it is ready. You can still DM
cryptkeeper here and ask for a manual invite. The slack URL is
byteball.slack.com
