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).
(as I noted in the buried thread)
The mental model being applied appears to be sculpting the community in the manner of sculpting marble with a hammer and chisel. Whereas how it'll work will be rather more like sculpting human flesh with a hammer and chisel. Giving rather a lot of side effects and not quite achieving the desired aims. Sculpting online communities really doesn't work very well. But, geeks keep assuming the social world is simple, even when they've been in it for years.
