If low effort, only because it's obvious to anyone who is paying attention. If useless, only because it's been repeated so many times by so many people.
It's low effort because it took you 10 seconds to think it and write it.
And LW isn't "mine" in any meaningful sense. I try to fix things that are mine
Seems to me there is little reason for you to offer advice at all, then.
Perhaps you ought to start a thread proposing bans on obvious feedback from users below X karma?
I've gotten sufficient evidence from support that voiceofra has been doing retributive downvoting. I've banned them without prior notice because I'm not giving them more chances to downvote.
I'm thinking of something like not letting anyone give more than 5 downvotes/week for content which is more than a month old. The numbers and the time period are tentative-- this isn't my ideal rule. This is probably technically possible. However, my impression is that highly specific rules like that are an invitation to gaming the rules.
I would rather just make spiteful down-voting impossible (or maybe make it expensive) rather than trying to find out who's doing it. Admittedly, putting up barriers to downvoting for past comments doesn't solve the problem of people who down-vote everything, but at least people who downvote current material are easier to notice.
Any thoughts about technical solutions to excessive down-voting of past material?
