Theymos' recent upgrade to some of the spam-heavy boards to reduce spam bumping seems to be working well, or at least as intended.  The strategy of adding a "bump-score" to threads to keep them closer to the top of the board is ingenious, in my opinion.  

It got me thinking about another possible application of a "score rating."  One for trolls.  I was thinking that a button on each user's profile page to tag that user as a troll could start to count towards that user's "Troll Score."  A similar approach to users' bumping power can be applied to the each user's troll-tagging power.  Again, a decaying effect of tagging someone as a troll could be applied to reduce it's long-term affects on that user's profile.

Then come some restrictions to the trolls:  If their troll-score gets too high they are restricted from creating new threads.  Higher still, and a possible temp-ban is in order.  What do you guys think?
