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).
I've GOT IT! Eureka! Oh I'm a genius.
Let's make the moderation system on this site freemium. See, upon logging into the site, for every 100 positive karma you gain, you can make a single up or down moderation. However, if you purchase "rational coins" (by demonstrating the rational operation of our money system with your credit card) you are allowed to make a single moderation for each coin.
Furthermore, you will be able to purchase 'special ability kits' that would do various interesting things to help you out in the moderation wars.
And tons more!
What could possibly go wrong?
