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).
Who is "we"?
I think the percentage of "casual" users who participate on this site because they enjoy intelligent conversations on rationality-related topics while having no FAI agenda is non-negligible. I suspect that reinforcing the idea of equality between LW and FAI activism will make many of them leave. It may be a net negative even if LW's mission is FAI activism as there are positive externalities of greater diversity of both discussion topics and participant opinions (less boredom, more new ideas, better critical scrutiny of ideas, less danger of community evaporative cooling, greater ability to attract new readers...)
Also, I don't like the idea of LW's mission being FAI activism. There is still written in the header: "A community blog devoted to refining the art of human rationality", and I'd appreciate if I could continue believing that description. Of course I realise that the owners of the site are FAI enthusiasts, but that's not true about the community as a whole. LW is a great rationality blog even without all its FAI/philanthropy stuff, not only for the texts already written, but also for the productive debating standards used here and a lot of intelligent people around. I would regret if I had to leave, which I would if LW turned to a solely FAI activist webpage.
