FIX: Only show the review page to users that can see it. Do not publish the reviewable count update message to everyone. (PR #9556)

Looks good, thanks! I added a couple of trivial comments.

nitpick but I would call this something different than can_ - something simple like ensure_can_see would be closer to the operation.

    return if user_ids.blank?

blank? here will work if it’s nil too - just in case. More defensive.
