Adjutant Reflex
From Halopedia, the Halo wiki
AdjutantReflex is a Forerunner artificial intelligence located on the Bungie.net and Halo.Bungie.Org forums. It has admitted to hacking into the Bungie servers, although it says it has no hostile intentions. It calls itself a facilitator of "Array requirements" to make sure "they are in flux". It appears that these Arrays may be Halos based on the amount of time the A.I. presented when asked how long ago the last Array event occured.
