By that I mean it's not being done, and you've proposed no change to cause it to happen.
But it is being done (even if i am the only one doing it -- it is being done). And the fact that i have proposed nothing to change it is my point: i see this whole issue as a solution looking for a problem.

... but enough of them aren't that trolls continue to get big responses.
And i fully believe that they will continue to get big responses even if you label the post as potentially trollish. But that's just my opinion.

You're asking people to navigate (without providing a nearby link) to another page to take an action on the current one.
If our audience was one of typical non-programming computer users who barely know how to read a manual and fix basic problems on their computers, then i would agree with this. But our audience is not. The core audience is experienced Perl programmers. Thanks to tabbed browsing, this is much easier than you say it is not. Most of the less-experienced users you speak of are here to ask questions, not answer them. It's the experienced users who will be answering the questions, giving feedback, etc. It is they who will be potentionally replying to trollish posts.

I don't know what you're referring to. There's no labeling option in consideration.
But there is. When you consider a node you have the option to give the reason why. That text appears on the content for the reaped node. See? You already have a way to label a post as trollish and as an added benefit, everyone else with consideration power (that is, those who are not the "less-experienced") can cast their vote as to whether or not they agree that it is trollish.

Again ... take a look at who is doing the responding. We are mature, experienced Perl programmers. If we take the bait and feed a troll, we know what the consequences will be. The consideration process was put into place years ago to handle this problem, and i fully believe that it is handling the problem as best as anything can. If a human cannot always determine 100% of the time that a post is truly a trollish post, how can a program do the same? Some people just can't get enough of that negative attention, and no system is going to stop the occasional trollish node from being posted.
