Why was one edit war party blocked and the other rewarded? 

Why was Arzel blocked for edit warring at Fox News Controversies while PrBeacon who also participated in the edit war, reverting Arzel twice in the last 24 hours, left alone and granted his wish to block his edit warring partner?  Surely Arzel wasn't blocked because he had 3 reverts in a 24-hour period instead of the 2 reverts of PrBeacon?
