Randy Farmer did an interview with "Community Management" - where he talked about the importance of minimizing the effects of vandalism. Yahoo Answers solved their spam issue by using the community to move from 12 hours to 30 second response times. http://thefarmers.org/Habitat/2008/06/randy_interviewed_on_community.html http://thefarmers.org/Habitat/2008/06/randy_interviewed_on_c... (video and transcript) I've been interested in this question myself for userscripts.org The question seems tied to a reputation system (to determine who is allowed to moderate). Joel and Jeff of Stack Overflow discuss reputation systems in a recent podcast: http://blog.stackoverflow.com/2008/10/podcast-26/ http://blog.stackoverflow.com/2008/10/podcast-26/ Which makes the question for me: how do you implement a reputation system on an existing site without pissing off users? Small details can lead to large consequences for your users, and when you have 6MM pageviews a month and 50K+ users, it seems like the wrong place to learn by making mistakes. Perhaps transparency around actions performed by the community moderators, so those who weren't granted new powers can provide a check against abuses. Providing a mechanism to view deleted comments/userscripts (but not who as to limit retribution), others can alert admin (me) if moderation needs reversed. Anyone have experience adding community moderation to an existing popular site?
