I'm not sure I agree with removing duped people, but there are a few easy ways perhaps to cut down on the 'glory' that is the worst node list.

We've already removed the negative number from people's experience and have replaced it with 'requires penance' or somesuch. I think we could do the same for these nodes. Why not just have it say something non-numeric in the worst nodes table? We also don't need to have it sorted per se. A bad node is a bad node. Does it really matter if it's the WORST of the worst nodes as compared to the SECOND worst?

Make those two changes and the worst node table is a quick ref of the worst nodes, in no particular order.
