Great idea to control trolls. They are the real cancer of forums. http://en.wikipedia.org/wiki/Hellbanning IMHO this should be core in XenForo 1.4. I got this idea from another forum (+18 so I don't link it) "I think a better refinement would be to make their posts visible to the other users with the same status. That way they can just troll each other and they may not even realize what happened, since occasionally their posts will still get responded to."
