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?
Someone spending their precious time going through someone's history to decrease their near-meaningless number as much as they possibly can is already losing. I hear about this happening so infrequently, and it's so totally inconsequential, that I don't think it merits thinking up/making changes to anything.
The problem is that it isn't meaningless. I was in the middle of a rather interesting ethical discussion, and many of my posts that I had just made went from 0 to -1, potentially dropping off of the radar of other readers. All it takes is two users colluding (or one user with an additional sock account) to effectively shut down someone else's entire voice.
If a post goes from 4 to 3, that isn't a big deal, but if it drops below the minimum display threshold before anyone gets a chance to read it, the entire flow of conversation gets disrupted.
