I wonder if trolls can be categorized automatically. Caveats and all, trolls are characterized by their participation in negative-karma two-person conversations and down-voting of their comments by a diverse and changing set of users. A simple learning algorithm should zap the predictable ones. Trolls are nourished by attention and early detection and removal should nip that behavior in the bud.

I've thought a lot about that. I wouldn't be surprised if current spam filters would work unchanged. There are not enough trolls on News.YC to make it worth investing time in such countermeasures, but it would be an interesting experiment to see if you could use statistical filtering techniques to detect trolls in some large public corpus like Digg or Reddit or Slashdot comment threads.
