+/// Activities are sent to the community itself if it lives on another instance. If the community

+/// Activities are also sent to those who follow the actor (with exception of moderation activities).

+/// * `actor` - The user who is sending the activity
+/// * `community` - Community inside which the activity is sent
+/// * `inboxes` - Any additional inboxes the activity should be sent to (for example,
+///               to the user who is being promoted to moderator)
+/// * `is_mod_activity` - True for things like Add/Mod, these are not sent to user followers
