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.
It is perhaps worth remembering that the original stated purpose of downvotes was to allow LW users to weed out low-quality contributions/contributors in an egalitarian fashion (that is, without the need for privileged users to perform privileged acts of weeding).
Consider an egalitarian mechanism X that allows a community to keep out low-quality contributors. The only way I can think of for such a community to prevent a rogue agent A from using X to keep out high-quality contributors is to ensure that the bulk of the community can tell the difference, agrees on the difference, and is prepared to use X accordingly. Once the community has reached the point where the amount of X-use A can invoke in a particular area is a significant fraction of the total amount of X-use the community as a whole invokes in that area (for example, if A bulk-downvotes user B, and the net downvotes thus created are a significant fraction of the total votes for B), X will predictably fail to keep out low-quality contributors. (Shortly past that point, X will predictably start to be used to keep out high-quality contributors.)
The discussion thus far has mostly de-facto agreed to this, and is therefore taking it for granted that egalitarian mechanisms won't cut it anymore... admins have to step in and clean things up. Which I in some theoretical sense agree with, though as with all such "someone else ought to do a bunch of extra work!" solutions, I don't especially feel entitled to benefit from its implementation.
Your comment seems to be an exception, though, which is interesting.
If I'm understanding you correctly, your position is that since downvoting has been corrupted we need a new egalitarian mechanism, such as calling out jerks, and that if we all use that mechanism reliably we can clean up the community.
Which leads me to ask: once we establish that convention, and rogue agents therefore start (incorrectly) calling out valuable contributors for being jerks, what ought we do then?
Well, not exactly. I'm not proposing "calling out jerks" as an alternative to downvoting as a mechanism for weeding out low-quality contributions. I'm saying that there are different kinds of contributions to the community that we want to discourage. We want to discourage poor-quality comments, of course, and I s... (read more)
