The recent implementation of a -5 karma penalty for replying to comments that are at -3 or below has clearly met with some disagreement and controversy. See http://lesswrong.com/r/discussion/lw/eb9/meta_karma_for_last_30_days/7aon . However, at the same time, it seems that Eliezer's observation that trolling and related problems have over time gotten worse here may be correct. It may be that this an inevitable consequence of growth, but it may be that it can be handled or reduced with some solution or set of solutions. I'm starting this discussion thread for people to propose possible solutions. To minimize anchoring bias and related problems, I'm not going to include my ideas in this header but in a comment below. People should think about the problem before reading proposed solutions (again to minimize anchoring issues).
Can someone please provide hard data on trolling, to assess its kind and scale? I can only remember a single example of repeated apparent trolling - comments made by private_messaging and presumed sockpuppets. I'm not very active though, and miss many discussions while they're still unvoted-on.
Seconded. The first time that I saw any indications of LW having a troll problem was a couple of days back, when people started complaining about us having one.
