Nice strawman.
What am I portraying you as saying that differs from what you're actually saying? I'm certainly not intentionally putting up strawmen. (If you mean the thing where I agree below that I should have been more explicit, then, er, I agree.)
Sense 1 and Sense 2 can't be reliably distinguished from the outside.
Indeed they can't, but they are still different things; it's reasonable to have different attitudes towards #1 becoming a community norm and towards #2 becoming a community norm; and what encourages #1 and what encourages #2 might be different.
It's an objection against naming people without providing reliable evidence.
You're right -- I should have said "complaining and providing names". Sorry about that. I shall edit my comment to clarify.
do it by changing the system, not by taking justice in your own hands.
In what way do you think I'm taking justice into my own hands? What do you think anyone concerned can actually, realistically, do to change the system?
(In principle, one could change the system by changing how the LW karma system works in a way that eliminates the possibility of anonymous mass-downvoting. In practice, so far no one has proposed a change that would accomplish this and so far as I know no one knows of any such change that would work well. And in practice, even with such a change fully designed it would then be necessary to arrange for it to be incorporated into the LW codebase; it is reasonable to suspect that the odds of that are not good.)

This is one of the conversations I was hoping ...
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.
