+/// * `activity` - The activity which is being sent

+/// * `community` - Community inside which the activity is sent
+/// * `inboxes` - Any additional inboxes the activity should be sent to (for example,

+/// * `is_mod_activity` - True for things like Add/Mod, these are not sent to user followers
