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 don't have a phone, and if I did I would refuse to give it out in case someone did something horrible like call me. I'm not the only phone-hater around; we overlap with phone-hater demographics a fair amount.
How would you feel about the $5 per account option?
Any other ideas on how someone could signal that the account they are creating is not yet another sock puppet or identity reset that you would be comfortable with? Maybe associating your account with your website?
I'm thinking the phone idea, if it is used at all, should be one of several options, so the user can choose one that works for them.
