   Another consideration: new installations should not allow open registrations by default. This should be a setting that the administrator needs to opt into, and this is a good place to inform them that open registration instances require moderation resources.

   In Mastodon, we display a warning when the admin chooses this option. Mastodon also support requiring moderator/admin approval for new sign ups, which helps a lot in preventing automated registrations.
