How about giving Ken his own thread that he is free to do with as he wants? But only in that thread. He is incapable of staying on topic anyway so in that one thread he could wander where he would (which he does anyway) and those who wanted to "have fun" with him could visit there but he couldn't litter other threads? Kind of keep him in the Ken Zone?
What do you think of my idea of just giving him a thread of his own. He wouldn't be allowed to muck up any other threads but he could have one thread that folks who chose could visit. I'd love to see him and Davidjay discuss stuff that would be like entertainment squared I think to get down and mathmatical with this.
