I met my last trolls on Google Buzz, so I created extension to Chrome which was (and still is ;-)) removing comments from those people from my stream. So even if they are writing something in other people Buzzes I simply didn't see it :-) [normal block in Buzz works only in this way that it blocks only given person from commenting on your posts].

So I think HTML based discussion areas aren't as bad ;-) you can still have tools for removing trolls comments. DOM is our friend here ;-)

Still, you'd have to write a similar Chrome extension if you meet your trolls again in a random blog's comment section.

Also, if everybody knows that everybody's news client has a killfile, then there is a stronger incentive not to troll than when all you know is that some clever developer could theoretically write a site-specific script to hide HTML comments.
