ACDBot is the aged guru leader of the other automatons that crawl along the dark underbelly of RationalWiki. It was created a long time ago, to help facilitate a large scale change in site structure. Before there was the "fun" namespace it was called "acd" an inside joke whose time was up. ACDBot changed all links to the ACD namespace into links to the fun namespace. After this tremendous job was completed he receded into retirement.
That is until a semi-unilateral decision was made to change all uses of "reference" sections into "footnotes." This task, being right up ACDBot's expertise it was called forth from retirement to once again aid in altering RationalWiki's idiosyncratic structural whims.
