I would like to say that the primary goal of wikipedia is not a to be a social experiment, but to build an encyclopedia. I am a strong (very strong) supporter of due process when it comes to good faith regular contributers, but in this case we all know what kind of a guy this is. 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
