Several people posted recently in a thread on women, mostly espousing feminist views - only to find that someone had declined to respond to their post, but instead browsed their history and downvoted every single comment or article they had ever posted.
I have two questions:
1. Why would you come to a site like this and pollute the karma system? How does it make you smarter? How does it make anyone else on the site smarter?
2. What would be a good technical workaround? In my mind, some system that detects mass-downvoting and flags a user for review would be preferable, but what should happen then? Should the system be more lenient to higher-karma posters? Who should perform the review process? What should be done with those whom the reviewer ascertains are abusing the karma system? I would prefer some kind of lesson that is more corrective than retributive - it seems to me that people who would perform this behavior are exactly the sort of people who need some of the lessons that this site provides. Any ideas?
An alternative would be to recognize that an upvote and a downvote are more orthogonal than opposite. A post or comment with 20 upvotes and 30 downvotes is clearly a very different post than one with 0 upvotes and 10 downvotes. A user with 2000 upvotes and 1500 downvotes is clearly a very different user than a user with 25 upvotes and 500 downvotes. If lesswrong simply reported upvote and downvote tallys side by side rather than netting them, a lot more information about posts, comments, and users would be available to readers. The current system is incapable of distinguishing between morons, trolls, intelligent newbies, and valuable and intelligent gadflies. Reporting positive and negative votes separately would help a lot.
