Below is a message I just got from jackk. Some specifics have been redacted 1) so that we can discuss general policy rather than the details of this specific case 2) because presumption of innocence, just in case there happens to be an innocuous explanation to this.
Hi Kaj_Sotala,
I'm Jack, one of the Trike devs. I'm messaging you because you're the moderator who commented most recently. A while back the user [REDACTED 1] asked if Trike could look into retributive downvoting against his account. I've done that, and it looks like [REDACTED 2] has downvoted at least [over half of REDACTED 1's comments, amounting to hundreds of downvotes] ([REDACTED 1]'s next-largest downvoter is [REDACTED 3] at -15).
What action to take is a community problem, not a technical one, so we'd rather leave that up to the moderators. Some options:
1. Ask [REDACTED 2] for the story behind these votes
2. Use the "admin" account (which exists for sending scripted messages, &c.) to apply an upvote to each downvoted post
3. Apply a karma award to [REDACTED 1]'s account. This would fix the karma damage but not the sorting of individual comments
4. Apply a negative karma award to [REDACTED 2]'s account. This makes him pay for false downvotes twice over. This isn't possible in the current code, but it's an easy fix
5. Ban [REDACTED 2]
For future reference, it's very easy for Trike to look at who downvoted someone's account, so if you get questions about downvoting in the future I can run the same report.
If you need to verify my identity before you take action, let me know and we'll work something out.

So... thoughts? I have mod powers, but when I was granted them I was basically just told to use them to fight spam; there was never any discussion of any other policy, and I don't feel like I have the authority to decide on the suitable course of action without consulting the rest of the community.
Interesting. I didn't know about the x4 limitation. As that puts a natural limit on the downvoting I do not see any problem in principle with the 'mass' downvoting. If you do not have the freedom to actually spend your karma on (mass) downvotes, then the problem is not the downvoting but the limit.
The limit ensures that you downvotes need to be compensated by correspondingly valued contributions. If more people exercised their downvoting share this 'mass downvoting' wouldn't even have been noticable.
The problem may be that it is applied to individuals. But even though that can be perceived as unfair it is still strictly the choice available to the voter (not much different that voting on the popularity of people instead of comments which is seldom nowadays instead of in popularity (up)votes.
My proposal would be to either a) reduce the limit to x2 or b) change the limit to x1 ''per person'' (if that is possible easily).
This is conditional on attackers not artificially accumulating karma by upvoting themselves (via multiple accounts). Such self-voting can in principle be either detected or prevented by network flow algorithms like Advogato's ( http://www.advogato.org/trust-metric.html ) but that requires significant changes to the karma logic.
Note: I'm not afiliated with Advogato but I'd really like to see the basic principle (the network flow) be applied more to voting algorithms in general.
I tend to think of downvoting as a mechanism to signal and filter low-quality content rather than as a mechanism to 'spend karma' on some goal or another. It seems that mass downvoting doesn't really fit the goal of filtering content -- it just lets you know that someone is either trolling LW in general, or just really doesn't like someone in a way that they aren't articulating in a PM or response to a comment/article.
