He will not help build an encyclopedia, therefore he should be blocked, regardless of his crimes on the wiki itself. There are no absolute laws on wikipedia, and I think this is a valid use of WP:IAR

Actually IAR is not a policy at all, it's just an absurd joke, and the root of more foolishness than is worth discussing, not some sort of trump card. We DO have absolute laws on wikipedia, and they described at :
http://meta.wikimedia.org/wiki/Foundation_issues
A few that apply to this situation are: "Ability of anyone to edit articles without registering", "NPOV as the guiding editorial principle", and "Jimbo Wales as ultimate authority on any matter (this is changing; see Arbitration Committee, Board)".
This situation was NOT covered by blocking policy, and was a wrongful block by an admin. The proper procedure would have been a discussion on Amelekites talk page, and then perhaps a RfC or RfM.
