We disallow repeating a notice (or whatever) if the scope of the notice is too private. So, only notices that are public scope (available to everyone in the world) or site scope (available to everyone on the site) can be repeated. Enforce this rule at a low level in Notice.php, and in the API, commands, and Web UI. Repeat button doesn't appear on tightly-scoped notices in the Web UI.
