I'm just tired of the signal pollution, and would like to be able to use karma to honestly appraise the worth of my articles and posts, without seeing 80% of my downvotes come in chunks that correspond precisely to how many posts I've made since the last massive downvote spree.
EDIT to add data points:
Spurious downvoting stopped soon after I named a particular individual (not ALL downvoting stopped, but the downvotes I got all seemed on-the-level.)
One block of potentially spurious downvoting occurred approximately one week ago, but then karma patterns returned to expected levels. I consider this block dubious, because it reasonably matches what I'd expect to see if someone noticed several of my posts together and disagreed with all of them, and did not match the usual pattern of starting with the earliest or latest post that I had made and downvoting everything (it downvoted all posts in a few threads, but not in other threads), so I'm just adding for completeness.
Spurious, indiscriminate downvoting started up again approximately half an hour ago on Sunday (12/1/2013), around noon MDT.
Edit: And now on Tuesday, 12/3/2013, at 10 AM, I'm watching my karma go down again... about 30 points so far.
Edit: And now on Saturday, 12/14/2013, at 2 PM, I'm watching my karma go down again... about 15 points so far, at a rate of about 1-2 points per second.
I doubt that. Many people here have long comment histories. You don't simply happen to notice most old comments, but if you're so inclined and have the time, clickfest awaits.
Silence already is the norm. "By the way I downvoted all your comments because of X." How do you expect that to go?
What amount of bad comments would be a reasonable threshold for downvoting someone's every comment? 50 percent? 20 percent? Should there be guidelines for that?
My own standard for downvoting a user as a category is "Would Less Wrong be better off if this user went away?" It's possible that there's some threshold percentage that causes me to arrive at that judgement, but if so, I don't know what that threshold is.
My suggested guideline is: if LessWrong would be better off if user X went away, downvote user X's comments.
