And no, sorry, we should not just ignore the "do my job" posts
Suddenly I have an idea, +1 point for correct moderator alerting. -1 for wrong alerting, to prevent people who will alert just to have points. 
Or special badges "I have alerted" (1), "In a alerting mood" (10), "Alert hero", "Alert hero +", but still -1 for every wrong alerting.
